In this booklet, top scientists within the fields of sensory biology, neuroscience, physics and engineering discover the elemental operational rules and behavioral makes use of of circulate sensing in animals and the way they may be utilized to engineering functions akin to independent keep an eye on of underwater or aerial vehicles.
Although people own no flow-sensing skills, numerous aquatic (e.g. fish, cephalopods and seals), terrestrial (e.g. crickets and spiders) and aerial (e.g. bats) animals have circulate sensing talents that underlie extraordinary behavioral feats. those comprise the facility to stick to silent hydrodynamic trails lengthy after the trailblazer has left the scene, to shape hydrodynamic photographs in their surroundings in overall darkness, and to swim or fly successfully and easily within the face of destabilizing currents and winds.

2010a, b). Thus, the study of flow sensing is a vibrant field of research for sensory ecologists and neuroethologists, and also for technologists working on biomimetic sensor design (Casas et al. 2013). Studies on flow sensing, particularly those at small scale around single sensors, require high spatial precision and nonintrusive measurement methods. Thus, noncontacting measurement methods such as Laser Doppler Anemometry (LDA), Laser Doppler Vibrometry (LDV), and Particle Image Velocimetry (PIV), originally developed by aerodynamics and fluid mechanics engineers, have been used to measure flows of biological relevance.
2011). The projection of each hair into the central nervous system forms a functional map of the current air direction that translates the origin of the incoming flow as three-dimensional spatio-temporal activity patterns (Jacobs et al. 2008). e. in opposite directions. This has important consequences for the overall computation of the direction of the incoming perturbation as these two effects might cancel each other. We also observed that the flow amplitude was substantially lower close to the surface of the abdomen than further away (Fig.
