  • Flow field perception based on the fish lateral line system
    • Authors: Yonggang Jiang; Zhiqiang Ma Deyuan Zhang
      First page: 041001
      Abstract: Fish are able to perceive the surrounding weak flow and pressure variations with their mechanosensory lateral line system, which consists of a superficial lateral line for flow velocity detection and a canal lateral line for flow pressure gradient perception. Achieving a better understanding of the flow field perception algorithms of the lateral line can contribute not only to the design of highly sensitive flow sensors, but also to the development of underwater smart skin with good hydrodynamic imaging properties. In this review, we discuss highly sensitive flow-sensing mechanisms for superficial and canal neuromasts and flow field perception algorithms. Artificial lateral line systems with different transduction mechanisms are then described with special emphasis on the recent innovations in the field of polymer-based artificial flow sensors. Finally, we discuss our perspective of the technological challenges faced while improving flow sensitivity, durability, and sensing fusi...

  • Aerodynamic effects of varying solid surface area of bristled wings
           performing clap and fling
    • Authors: Mitchell P Ford; Vishwa T Kasoju, Manikantam G Gaddam Arvind Santhanakrishnan
      First page: 046003
      Abstract: The smallest flying insects with body lengths under 2 mm show a marked preference for wings consisting of a thin membrane with long bristles, and the use of clap and fling kinematics to augment lift at Reynolds numbers (Re) of approximately 10. Bristled wings have been shown to reduce drag forces in clap and fling, but the aerodynamic roles of several bristled wing geometric variables remain unclear. This study examines the effects of varying the ratio of membrane area ( A M ) to total wing area ( A T ) on aerodynamic forces and flow structures generated during clap and fling at Re on the order of 10. We also examine the aerodynamic consequences of scaling bristled wings to Re  =  120, relevant to flight of fruit flies. We analyzed published forewing images of 25 species of thrips (Thysanoptera) and found that A M / A T ranged from 14% to 27%, as compared to 11% to 88% previously reported for smaller-sized fairyfl...

  • A force-measuring and behaviour-recording system consisting of 24
           individual 3D force plates for the study of single limb forces in
           climbing animals on a quasi-cylindrical tower
    • Authors: Aihong Ji; Shanshan Yuan, Thomas Endlein, Iain D C Hill, Wei Wang, Huan Wang, Nan Jiang, Zhihui Zhao, W Jon P Barnes Zhendong Dai
      First page: 046004
      Abstract: This study describes the design of a new force measuring array with a quasi-cylindrical surface for measuring the 3D ground reaction forces of animals climbing on a surface with high curvature. This force-measuring array was assembled from 24 individual 3D force sensors, each with a resolution at the millinewton (mN) level, which were installed from top to bottom in four columns and six rows, with sensors in neighbouring columns staggered in height. Three cameras were used to simultaneously record the climbing behaviours of animals (in these experiments tree frogs) on the cylinder-like force measuring array. We were thus able to simultaneously record the ground reaction forces of each of the four limbs of tree frogs (here six individuals of the Chinese gliding or flying frog, Rhacophorus dennysi , with forelimb spans in the range 163–201 mm) climbing or descending both smooth and rough surfaces on a quasi-cylindrical structure with an overall diameter of 79 mm. We describe...

  • Evaluation of silicone elastomers as structural materials for
           microstructured adhesives
    • Authors: Aiva Simaite; Matthew Spenko
      First page: 046005
      Abstract: Microstructured (sometimes referred to as gecko-like) adhesives have numerous advantages over flat films, especially for practical applications on non-ideal surfaces that may be uneven or contaminated with dust. However, due to interdependence among material surface and bulk properties, the best material to fabricate such adhesives is still unknown. In this work, we analyzed eleven commercially available silicone elastomers to evaluate their use as flat and microstructured adhesives to address multiple material related questions that may impact the choice of the ‘best’ material for microstructured dry adhesives. To illustrate the applicability of the measured properties to modeling microstructured surfaces, we use stalk-shaped microstructures, whose contact mechanics are well understood. We demonstrate that there is no correlation between the adhesion strength of flat and microstructured adhesives; while bulk dissipation is the most important factor influencing the adhesion stre...

  • Analysis of the role of wind information for efficient chemical plume
           tracing based on optogenetic silkworm moth behavior
    • Authors: Shunsuke Shigaki; Shoma Haigo, Cesar Hernandez Reyes, Takeshi Sakurai, Ryohei Kanzaki, Daisuke Kurabayashi Hideki Sezutsu
      First page: 046006
      Abstract: Many animals use olfactory information to search for feeding areas and other individuals in real time and with high efficiency. We focus on the chemical plume tracing (CPT) ability of male silkworm moths and investigate an efficient CPT strategy for an autonomous robot. In the case of flying insects, the wind direction is an important factor in CPT, because the wind carries odors amongst other environmental information. However, whether the same phenomenon occurs in the walking silkworm moth has not been investigated. Therefore, we examine how the silkworm moth uses wind information during CPT. To accurately investigate the response to the wind direction, we introduce an optogenetic approach that replaces the odor stimulation with light stimulation, allowing us to separate the ‘wind stimulus’ from the ‘odor stimulus’. We examine how the moth uses wind direction information in a biological experiment, and find that the movement speed is significantly reduced when the wind speed i...

  • Biomimetic 3D printed lightweight constructions: a comparison of profiles
           with various geometries for efficient material usage inspired by
           square-shaped plant stems
    • Authors: Ruwen Kaminski; Thomas Speck Olga Speck
      First page: 046007
      Abstract: Within a bottom-up approach in biomimetics, this study was inspired by the plant motherwort ( Leonurus cardiaca ), which has stems divided longitudinally into hollow internodes and solid nodes, a lightweight concept well-known in biology. The square cross-sections show a specific geometric arrangement of various tissues, each with different mechanical properties. We have used CAD software and selective laser sintering technology to produce (1) extruded hollow profiles with various cross-sections analogous to internodes, and (2) integrated additional elements mimicking nodes. The design of the individual profiles with their different geometries is based on an increasing degree of abstraction, starting with profile A, which comes closest to the plant model, through profile B in the form of a greatly simplified material distribution, to profile C with the simplest geometry of a square hollow profile. In the context of resource-saving constructions, we have determined the flexu...

  • A minimal longitudinal dynamic model of a tailless flapping wing robot for
           control design
    • Authors: K M Kajak; M Karásek, Q P Chu G C H E de Croon
      First page: 046008
      Abstract: Recently, several insect- and hummingbird-inspired tailless flapping wing robots have been introduced. However, their flight dynamics, which are likely to be similar to that of their biological counterparts, remain yet to be fully understood. We propose a minimal dynamic model that is not only validated with experimental data, but also able to predict the consequences of various important design changes. Specifically, the model captures the flapping-cycle-averaged longitudinal dynamics, considering the main aerodynamic effects. We validated the model with flight data captured with a tailless flapping wing robot, the DelFly Nimble, for air speeds from near-hover flight up to 3.5 m s −1 . Moreover, the model succeeds in predicting the effects of changes to the center of mass location, and to the control system gains. Hence, the model is suitable even for the initial control design phase. To demonstrate this, we have used the simulation model to tune the robot’s control sy...

  • Numerical prediction of aerodynamic performance for a flying fish during
           gliding flight
    • Authors: Jian Deng; Lingxin Zhang, Zhiyou Liu Xuerui Mao
      First page: 046009
      Abstract: Flying fish is a family of unique aerial–aquatic animals, which can both swim in the water and glide over the sea surface. Most previous studies on their aerodynamic characteristics were based on field observations or measurements of their morphometric parameters. In the present study, we consider three different flying fish models, of which the preliminary one mimics the Cypselurus hiraii in the pectoral fin morphology, following a previous wind tunnel experiment (Park and Choi 2010 J. Exp. Biol . 213 3269–79). Their aerodynamic performances are numerically studied by the computational fluid dynamics (CFD) method. The maximum lift force coefficient of 1.03 is reached at the angle of attack ##IMG## [http://ej.iop.org/images/1748-3190/14/4/046009/bbab23e6ieqn001.gif] , and the maximum lift-to-drag ratio of 4.7 is achieved at ##IMG## [http://ej.iop.org/images/1748-3190/14/4/046009/bbab23e6ieqn002.gif] .

  • Computational investigation of wing-body interaction and its lift
           enhancement effect in hummingbird forward flight
    • Authors: Junshi Wang; Yan Ren, Chengyu Li Haibo Dong
      First page: 046010
      Abstract: A lift enhancement mechanism due to wing-body interaction (WBI) was previously proved to be significant in the forward flight of insect flyers with wide-shape bodies, such as cicada. In order to further explore WBI and its lift enhancement effect in a flapping flight platform with different wing and body shapes, numerical investigations of WBI were performed on the forward flight of a hummingbird in this paper. A high-fidelity computational model of a hummingbird in forward flight was modeled with its geometric complexity. The wing kinematics of flapping flight were prescribed using experimental data from previous literature. An immersed-boundary-method-based incompressible Navier‒Stokes solver was used for the 3D flow simulations of the wing-body system. Analyses on aerodynamic performances and vortex dynamics of three models, including the wing-body (WB), wing-only (WO), and body-only (BO) models, were made to examine the effect of WBI. Results have shown significant overall l...

  • Umbrella leaves—Biomechanics of transition zone from lamina to
           petiole of peltate leaves
    • Authors: Moritz Sacher; Thea Lautenschläger, Andreas Kempe Christoph Neinhuis
      First page: 046011
      Abstract: In this study we aim to show how the peltate leaves of Colocasia fallax Schott and Tropaeolum majus L., despite their compact design, achieve a rigid connection between petiole and lamina. We have combined various microscopy techniques and computed tomography (CT) scanning for the analysis of the basic structure of the plant’s stabilization system. Mechanical tests yielded key mechanical parameters and allowed us to assess the mode of failure. The results of the tests were further processed in a finite element method (FEM) analysis. We were able to show that both plants are able to endure high loads irrespective of the different composition of the supporting structure. C. fallax forms many separate branched strands, whereas T. majus forms fewer strands of greater diameter interconnected in the centre of the transition area, forming a bundle of irregular orientation. This results in different ways to dissipate loads on the lamina. In C. fallax w...
