  • Design and Analysis of Various Characteristics of a MEMS-Based
           PIB/CNT/LiNbO3 Multilayered SAW Sensor for CO2 Gas Detection

    • Free pre-print version: Loading...

      Abstract: Abstract This paper presents the design and analysis of a surface acoustic wave (SAW) sensor with a multilayer nanocomposite to detect carbon dioxide (CO2) gas. SAW resonator impacts the detection and identification of hazardous gases that exist in the environment in an uncontrolled manner. These devices have the operational capability to work in a very extreme elevated temperature, pressure, and inert noxious atmosphere. The proposed work is intended to provide a two-dimensional model of a surface acoustic wave device/sensor and the most prominent solid material, carbon nanotube (CNT), which plays a vital role in the adsorption of volatile organic compounds. However, another miniature sensor has been designed with a potential material, an organic polymer, i.e., poly-isobutylene (PIB). Both the sensor model responses were examined for CO2 gas at room temperature. In this work, we have designed two different resonator structures with the help of COMSOL Multiphysics. The proposed, designed models were patterned with interdigitated transducer electrodes made of aluminum material coated explicitly on top of the structure were used to analyze gas sensing behavior for CO2 gaseous elements. Here the proposed geometry provides resonance of 9.1524 MHz and anti-resonance of 9.2455 MHz for monolayer structure and resonance of 8.6447 MHz, and anti-resonance of 8.5201 MHz for multilayer structure. Comparatively, the second sensor PIB/CNT/LiNbO3 heterostructure pattern was also designed to be the best choice for the accurate and reliable measurement of the concentration of various gaseous elements based on a few parameters are discussed further.

  • Extensive Analysis of Gate Leakage Current in Nano-Scale Multi-gate
           MOSFETs

    • Free pre-print version: Loading...

      Abstract: Abstract Excessive gate leakage is crucial for nanoscale metal oxide semiconductor field-effect transistors (MOSFETs), resulting in unnecessary static power dissipation and switching delay. Herein, we used three-dimensional modeling to understand the gate leakage behavior of various nanoscale MOSFETs, including fin field-effect transistor and gate all around MOSFET. We used Wentzel–Kramers–Brillouin approximation to compute the direct quantum tunneling-based gate leakage current. We performed all computations of quantum transport for gate leakage current through the non-equilibrium Greens function approach. Among the MOSFET structures under study, the gate all around MOSFET demonstrates the most profound gate leakage deviation with the gate material work function and oxide thickness. A detailed analysis of the dependence of the gate leakage on the metal work function is presented, and the charge density model is used to explain this dependence. This work explores the possibilities of controlling the gate leakage through gate material variations in different nanoscale multi-gate MOSFET architectures.

    • Free pre-print version: Loading...

      Abstract: Abstract A low profile wearable antenna for the different applications of Body Area Networks is presented. Wearable microstrip patch antenna for development in different applications in the area of WBAN. Many breakthroughs of wearable devices, together including their flexibility, suggest a real time monitoring with WBAN technology of the human vital signs such as pulse rates, blood pressure, and body temperature. The proposed antenna works in the operating frequency of 2.45 GHz which falls under the industrial, scientific and medical (ISM) frequency band. The designed antenna uses the flexible Polyimide substrate with a relative permittivity of 3.5 and thickness of 0.1 mm. The antenna is tested on a three layered human phantom model. The antenna parameters of return loss, VSWR, Specific Absorption Rate (SAR), gain and low value are established, while Return lost at 2.45 GHz is approximately − 23.22 dB with a VSWR value of 2.45 GHz being 1.13, which determines improved matching impedance. The 2D and 3D gain, and radiation patterns have been determined. The designed antenna is simulated with a three layered phantom model using a High Frequency Structure Simulator (HFSS).The simulated model is tested using Network Analyzer and Anechoic chamber and fabricated.

    • Free pre-print version: Loading...

      Abstract: Abstract This article consists of two research parts. The first one presents results of calculation and optimization of Angelov model parameters compared to the experimental values of the intrinsic elements and the Ids–Vds model of a Gaussian signal transistor HEMT. The device has two fingers gate of 0.25 mm of each one. The gate width is also equal to 0.5 mm and the gate length is of 0.5 μm.

  • Energy Harvest System Research for High Precision Electronic Voltage
           Transformer based on Coupling Capacitance

    • Free pre-print version: Loading...

      Abstract: Abstract High quality power is the prerequisite for high precision measurement of an electronic voltage transformer. In order to ensure a compact structure and stable operation of the transformer, this paper proposes a circuit and high voltage energy harvest of high precision electronic voltage transformer based on coupling capacitance. The energy extraction circuit is directly connected with the high voltage terminal through a capacitor, and the low DC voltage is obtained through the diode rectifier bridge. A self-holding duty cycle regulating circuit is installed on the DC side, and the power required by the load can be automatically adjusted to match the load. Because the overall load of the power extraction circuit is capacitive, there is no ferro-resonance problem. Furthermore, there is also no MCU in the device, so that the whole circuit has the advantages of small power loss, small volume, strong anti-interference ability, and can provide a stable DC power for the metering device. The proposed method is verified in simulations using PSCAD/EMTDC.

  • The Effect of Electronic Characteristics of Molecules in Ester Insulating
           Oils on Streamer Propagation

    • Free pre-print version: Loading...

      Abstract: Abstract Ester insulating oils are the preferred dielectric fluids of choice for oil-immersed transformers because of their superior fire safety, environmental friendliness, sustainability, and satisfying operating efficiency compared with traditional mineral insulating oil. However, the ease of streamer propagation and low breakdown voltage in ester fluids at positive lightning impulse (LI) voltage pose a crucial challenge to the safe operation of transformers, significantly limiting their use in power transformers. Currently, most available studies have focused on the morphological analysis of streamers without further investigation at the molecule level. In this work, we investigated the effect of ionization potential (IP) and electron affinity (EA) of molecules in three types of ester fluids—palm fatty acid ester (PFAE), soybean (FR3) and rapeseed (RDB) insulating oils—on streamer propagation at positive LI voltage. The calculated IP of PFAE oil (8.8 eV) is higher than the other two oils (7.5 eV). 66% faster streamer propagation and 25% lower positive LI breakdown voltage were found in PFAE oil compared with FR3 and RDB oils under positive LI voltage. Under the same applied voltage, the streamer in PFAE oil travelled faster and stopped at a farther distance than in FR3 and RDB oils. The lower EA and viscosity of PFAE oil equipped electrons with higher kinetic energy, leading to a fiercer collision between electrons and molecules and thus a large number of excited molecules. In contrast, relatively higher EAs and viscosities of FR3 and RDB oils limited electron-molecule collision, resulting in a lack of excited molecules for streamer propagation.

  • Design and Performance Analysis of Micropump for Drug Delivery Using
           Normal and Stacked Ring Type Piezoelectric Actuator

    • Free pre-print version: Loading...

      Abstract: Abstract In drug delivery systems micropump plays a very important role for controlled drug delivery. This paper presents the analysis of three designs of micropumps for drug delivery application, where each micropump design is analyzed with normal ring type piezo actuator (NPZT) and Stacked ring type piezo actuator (SPZT) individually. Now totally six different micropump designs are analyzed in this paper. The main objective of this paper is to distinguish the performance of micropump using NPZT and SPZT actuators on various designs, and advantage of using Ring type Piezoelectric (PZT) element over the use of conventional PZT disc as an actuator. With the use of ring type PZT element on membrane the uncovered region of the membrane undergoes more flexular displacement at center due to the radial contraction or expansion. All these micropumps are given a sinusoidal excitation of 90 V peak-to-peak at 100 Hz frequency. All performance parameters of micropump such as membrane deflection, flow rate, chamber pressure, settling time are analyzed as a function of time. In every design, micropumps actuated with SPZT shown improved flow rate without any further increase in voltage. Among all these designs the best one given an outlet flow rate of 800 μl/min, at a maximum flow velocity of 50 mm/sec, with a settling time of 60 ms.

           Biosensor Application

    • Free pre-print version: Loading...

      Abstract: Abstract This paper reports the performance assessment of vertical silicon nanowire TFET (V-siNWTFET) design for biosensor applications using dielectric-modulation and gate underlap technique. The sensitivity of the V-siNWTFET is recognizing by immobilizing the different biological molecules such as lipids, biotin, uricase, protein, Gox, streptavidin, uriease, zein etc. in the cavity region which is created under the gate electrode and source oxide. The performance analysis is observed by varying the relative permittivity of the different biomolecules and analyzes the parametric variation both for neutral and charged biomolecules. The sensitivity of the biosensor has been detecting in the terms of drain current (ID), threshold voltage (VTH), subthreshold slope (SS), transconductance (gm), and ION/IOFF ratio. The proposed device structure has capable to reduce the leakage currents and high sensitivity biosensor design in the nanoscale regimes. The obtained best optimum parameters of the proposed devices are ION (1.37E−08 A/µm), IOFF (9.44E−19 A/µm), SS (29.97 mV/dec) and ION/IOFF (4.29E + 10) ratio with gate work-function (ϕgate = 4.8 eV) and uniformly doped (1 × 10–19 cm−3) silicon nanowire at drain to source voltage (VDS = 1.0 V). The higher sensitivity of the proposed V-siNWTFET for Biosensor is observed for Zein biomolecules (K = 5).

  • Design and Investigation of Dual Dielectric Recessed-Gate AlGaN/GaN HEMT
           as Gas sensor Application

    • Free pre-print version: Loading...

      Abstract: Abstract This paper presents a highly sensitive Recessed Gate/source/drain AlGaN/GaN HEMT (RG-AlGaN/GaN HEMT) based Carbon Monoxide gas sensors. Many types of Carbon Monoxide (CO) gas sensor have already been demonstrated experimentally. The deeply etched recessed gate based HEMT form highly sensitive 2DEG for small change in gate metal oxide. Copper Oxide and Cerium Oxide are used as a gate electrode in CO gas detection and these metal oxides are reactively sensitive to CO gas molecules. Because of the change in the work function of gate metal oxide due to the presence of gas deposition on it, there is the change in Ioff, Ion, SS and Vth which can be taken as sensitivity parameter for sensing the gas molecules. For a change in work function till 700meV using various steps sizes, RG-AlGaN/GaN HEMT based CO gas sensor shows highly sensitivity with respect to device characteristics parameters.

      Abstract: Abstract The modified structure of BF-BNT (Bi0.5La0.5Fe)0.25(Bi0.5Na0.5Ti)0.75O3) single perovskite is prepared by a conventional solid-state reaction technique. The structural analysis suggests a tetragonal crystal with space group P4bm (JCPDS file No. 01-070-4760). The average crystallite and lattice strains are 87.2 nm and 0.116% respectively. The dielectric study predicts negative temperature coefficient of resistance character while the presence of low dielectric loss makes the materials useful for energy storage devices. The analysis of the modulus study suggests the presence of a non-Debye type of relaxation process while a thermally activated relaxation process is confirmed from the study of ac conductivity. The presence of the depressed semicircular arcs in both Nyquist and Cole–Cole plots confirms the semiconductor nature of the sample. The study of the Raman spectrum confirms the presence of all atomic vibrations. The UV visible study provides the energy bandgap of 1.67 eV, suitable for the different optoelectronic devices.

           Filter by Serpentine Shape Shunt/Open Stubs

    • Free pre-print version: Loading...

      Abstract: Abstract In this paper, the design and simulation of a new compact bandpass filter (BPF) has been implemented with serpentine meandershunt stub on coplanar waveguide technology. The inductive loading is improved by serpentine meander, thus the size of the BPF is reduced. The size of the proposed BPF structure is 4 × 2.6 mm2. The behaviour of the proposed structure and effects on the frequency response of BPF while changing the dimensions is carried out with an electromagnetic (EM) simulator. The equivalent circuit model describes the proposed BPF and exhibits the center frequency, bandwidth, and insertion loss of 20, 8 GHz, and< 0.1 dB respectively. The device-level and equivalent lumped model simulations are done by using the HFSS and ADStools. The proposed BPF is transformed into the bandstop filter, while the serpentine shunt type meander is convertedinto an open stuband also the coupling capacitance gap has vanished. The frequency response of bandstop filter (BSF) is also carried out with both EM and equivalent simulations, these simulations are disclosed the excellent agreement between the electromagnetic (EM) and lumped equivalent model simulations for both BPF and BSF over a frequency range of (15–30) GHz. Hence the proposed structure is recommended for K band (18–26) GHz applications.

  • Wear-Induced Attenuation on Transmission Lines and Their Causes

    • Free pre-print version: Loading...

      Abstract: Abstract In this paper, the radio frequency (RF) behavior of mechanically stressed coaxial and for the first time also twisted-pair transmission lines is investigated over their service life. The main goal is to enable predictive maintenance for cables in moving applications and avoid preventive replacement. This also reduces the use of high-cost resources. For this purpose, stranded and solid-core variants of coaxial and twisted-pair type cables are mechanically loaded on the two-pulley apparatus according to EN 50396. Their RF transmission (S21) behavior is measured using a vector network analyzer and presented over bending cycles. For the first time, the phase response of mechanically loaded transmission lines is evaluated with respect to their service life. Two significant causes for the increasing attenuation and altered phase response are identified: breakage in foil screen and increasing surface roughness on the copper conductors. The identified causes are supported with literature evidence. Through measurements and theoretical calculations, it is proven that the phase is much more suitable for an assessment of the remaining service life than the amplitude. The findings can be used to implement a cable monitoring system in industrial environments which monitors the lines in-situ and reminds the user to replace them, whenever a certain wear-level is reached.

  • A Novel Memristor Model for the Nonlinear Memristor Devices

    • Free pre-print version: Loading...

      Abstract: Abstract The functional characteristics of the real memristor devices are modeled through various mathematical approaches with/without window functions. Nevertheless, these models do not provide accurate performance metrics compared to physical memristor devices. In the backdrop of these prevailing issues pertaining to the modeling of memristors, we propose here yet another memristor model namely “Three Dimensional Voltage Adaptive Memristor (3DVAM)”, which provides a versatile solution to the nonlinearity in the ionic drift as well as the adopted parameters being matched with the physical memristor device. The proposed 3DVAM model is found to retain the expected nonlinearity with kinetic dopants by exhibiting the Pinched Hysteresis Loop (PHL) for large applied voltage [± 3 V ≤ v ≤ ± 13 V] without using the window functions. Interestingly, the flexibility of our proposed memristor model is proven by its adaptability with respect to applied frequency response at the highest being 10 MHz (lowest being 0.01 Hz) and that facilitates to enhance the degree of nonlinearity in current–voltage characteristics by the modality of the incorporation of 3D geometrical as well as material parameters for the first time. Thus, the 3DVAM model facilitates flexibility in fitting into other memristor models; it is proven by its compatibility with well-adapted VTEAM as well as linear ion drift models. Finally, the model offers high chip density and performs the logic operation for the applied voltage (v), which is as low as ± 0.45 V as compared to its CMOS counterpart.

  • Microsensor for Cancer Detection and MEMS Actuator for Cancer Therapy

    • Free pre-print version: Loading...

      Abstract: Abstract Cancer is a deadly disease that severely impacts patients' quality of life and puts emotional strain on their relationships. Cancer treatment can quickly deplete all the economic resources and opportunities and leave their families to handle extreme financial losses without guaranteeing patients' recovery. Early cancer diagnosis improves the patient's recovery rate with less expensive treatment. Currently, in practice, different methods for cancer detection exist, such as CT scan, MRI scan to biopsy of cells and performing molecular diagnostics by ELISA and PCR tests. The paper focuses on the MEMS-based biosensors and actuators that would perform to detect cancer and aid treatments. MEMS-based microcantilever is simulated to be used as a biosensor device to detect cancer by utilizing lower concentrations of biomarkers compared to the regular biopsy tests. MEMS-based microactuator that could vibrate in the resonant frequency of the cancer cell and work as an alternative cancer treatment. The actuator is aimed to carry out targeted evisceration without affecting normal cells due to the difference in chemical properties of cancer cells compared to the regular healthy human cell.

    • Free pre-print version: Loading...

      Abstract: Abstract Higher device reliability and lower device-to-device variability are needed to improve the density and yield of integrated circuits. A high pressure deuterium annealing (HPDA) process is proposed for this purpose. Gate-enclosed n-MOSFETs were fabricated on silicon substrate as test vehicles. Then, secondary ion mass spectrometry was performed to verify deuterium absorption. After that, device parameters such as gate leakage, threshold voltage, and subthreshold swing were measured, and the values before and after the HPDA process were compared. The results confirmed device reliability as well as device-to-device variability were improved by the proposed HPDA process.

  • Investigation of Structural, Photoluminescence and Thermoluminescence
           Properties of Scheelite-Type CaWO4 Phosphor

    • Free pre-print version: Loading...

      Abstract: Abstract This paper reports structural, optical, photoluminescence and thermoluminescence properties of scheelite-type CaWO4 ceramic synthesized by solid-state reaction route. X-ray diffraction study revealed the structure of the sample with tetragonal phase and I41/a (88) space group. Lattice parameters were calculated from the Rietveld refinement method and the crystal structure was observed using VESTA software. Photoluminescence excitation spectra were obtained by using 450 nm and 460 nm emission wavelengths. The emission spectra obtained with 240 nm excitation wavelength showed an emission band around 448 nm that can be ascribed to 1T2 to 1A1 optical transition of electrons within [WO4]2− group. CIE Chromaticity indicated that CaWO4 emits blue color and the color purity is also calculated. Optical band gap and urbach energy of the material were measured from the UV–visible spectroscopy. Thermoluminescence (TL) properties were investigated with different UV doses and the variations of TL emission peaks with temperature confirmed that CaWO4 has second-order kinetics with lower UV dosimetry.

  • High Power PV Array Emulator Based on State Feedback Controller Under
           Uniform and Non-Uniform Insolation

    • Free pre-print version: Loading...

      Abstract: Abstract Solar Photovoltaic (PV) energy has known an increased interest in the last years. However, its dependence on climatic conditions hinders PV researchers from carrying out their tests and experiences at the desired weather parameters of temperature (T) and solar insolation (G), in addition to the expensive cost of actual PV panels and the required large area. Therefore, the PV array emulator has been invented to reproduce faithfully similar PV characteristics and mimic the behavior of actual PV modules and arrays irrespective of environmental conditions change. This paper proposes thus a new PV source emulator based on a full-bridge converter controlled by a state feedback technique. The control strategy is based on the resistance-current characteristic of the PV array in order to ensure high accuracy of the emulation process. The main contribution of this work is the improvement of the accuracy (relative steady-state error is less than 1%), stability and dynamic response of the PV emulator compared to existing solutions since the current and voltage ripples of the proposed emulator do not exceed 0.8% while the outputs of some existing conventional emulators become unstable at certain conditions. Moreover, the designed system is able to reach higher peak powers than those obtained through conventional PV emulators (more than 7 kW). Simulation results using Matlab Simulink software are presented and discussed to highlight the performances of the proposed PV system under uniform irradiance and partial shading conditions.

  • Utilize the UV-Visible Region for Reduction of NO by Methylene Blue-Doped
           TiO2 for Photocatalysis

    • Free pre-print version: Loading...

      Abstract: Abstract A photocatalyst that can adsorb particulate matter (PM) with an electric charge is a popular method for PM reduction. Some commonly used photocatalysts comprise single metal oxides such as TiO2 and ZnO, which could be utilized under ultraviolet (UV) region. However, because UV region constitutes a very small part of the total wavelength of sunlight, technology needs to be developed that allows the utilization of the visible region as well. Herein, we developed a new organic material that activated under not only UV region but also visible region by utilizing methylene blue (MB) with TiO2. To make the TiO2–MB film adsorb well, we discuss various solvents, concentration controls, and even coating methods. By conducting NO removal test, we showed that it is possible to reduce the PM more effectively by using TiO2–MB film than that achieved using TiO2 alone.

           0.99Pb(Zr0.53Ti0.47)O3–0.01Bi(Y1 −xFex)O3 Ceramics for Application of
           Energy-Harvesting Devices

    • Free pre-print version: Loading...

      Abstract: Abstract Piezoelectrics of 0.99Pb(Zr0.53Ti0.47)O3–0.01Bi(Y1 − xFex)O3 (PZT-BYFx, 0 ≤ x ≤ 0.6) samples were investigated for energy-harvesting devices. In the sintering processes, the pre-synthesized PZT and BYFx powders were used to increase the piezoelectric properties. Compared with the PZT-BY samples, the PZT-BYFx specimens showed the larger grain size. The piezoelectric charge coefficient showed the maximum value at the Fe concentration of 0.3 molar ratio. Therefore, we checked the temperature dependency of the piezoelectric properties with the PZT-BYF03 composition. The ceramics were well sintered at the temperatures of 800–1200 °C and showed the maximum sintering density of 98.3% of the theoretical value. The transduction coefficient showed the maximum value of 2.0⋅10− 15 m2/N in the samples sintered at 1170 °C. And the values were decreased with decreasing the sintering temperature. The large transduction coefficient means that the PZT-BYF03 composition is a suitable material for energy harvesting applications.

  • Total Shielding Efficiency, Reflection Loss and Absorption Loss of
           Nanoparticles/Paraffin Wax Absorber in the Shielding of Electromagnetic
           Pollution

    • Free pre-print version: Loading...

      Abstract: Abstract The extensive development of diverse electronic/electrical systems has led to increased exposure to electromagnetic field and can result in many adverse effects on humans, other living beings, safety operation of various equipment, etc. Electromagnetic interference (EMI) shielding materials are in greater demand to suppress this electromagnetic pollution. The present study investigates the factors affecting the shielding efficiency of carbon black-based nanocomposite shields. Fe3O4/carbon black nanocomposite (CBN) with paraffin wax were fabricated by melt mixing methods in different weight percentages of the dispersants. The EMI shielding properties of the nanocomposites were measured using a vector network analyzer in the frequency range of 8.2 to 12.5 GHz (X band) based on the transfer/reflection method. The total shielding efficiency was used to assess the shield's protection performance. Based on the weight percentages of nanocomposite constituents, four samples were obtained. The highest average of total shielding efficiency in equal thickness belonged to the sample with 50% CBN and 15% Fe3O4 nanoparticles in weight. At different thicknesses, the highest average total shielding efficiency was related to the minimum thickness of 0.8 mm. Also, in with increasing the frequency decreased the mean total shielding efficiency in the samples. Depending on the type and weight percentage of nanocomposite compounds, one of the absorption or reflection mechanisms can be the main mechanism in reducing or eliminating electromagnetic waves in nanocomposite shields. The shield thickness and frequency of electromagnetic waves affect the protective performance of the shield.
