Abstract :
We have successfully developed biomimetic flow sensitive hair-sensor arrays taking inspiration from mechano sensory hairs of crickets. Our current generation of sensors achieves sub mm/s threshold air-flow sensitivity for single hairs operating in a bandwidth of a few hundred Hz and is the result of a few iterations in which the natural system (i.e. crickets filiform hair based mechano-sensors) have shown ample gui dance to optimization. Important clues with respect to mechani cal design, aerodynamics, viscous coupling effects and canopy based signal processing have been used during the course of our research. It is only by consideration of all these effects that we now may start thinking of systems performing a "flow-camera" function as found in nature in a variety of species.
