Bioinspired Haircell Receptive Sensors
Abstract
Artificial lateral line sensing technique inspired by the lateral line of fish has been developed through interdisciplinary collaborations among engineers, material scientists and biologists. Constituted by numerous superficial neuromasts and canal neuromasts, the lateral line of fish has been studied from both biological and engineering perspectives. By learning from the anatomic structure and the sensing mechanism of the biological system, superficial biomimetic neuromast (BN), canal BN, BN with artificial cupula, and artificial lateral line (ALL) have all been realized using MEMS technology and characterized under various flow conditions. The superficial BN has achieved unprecedented high sensitivity in fluid flow sensing. The canal BN demonstrated low-pass filtering and selective sensing capabilities. The artificial cupula pushed the BN's sensitivity to an even higher level. At the system level, different ALLs have been configured for some typical biologically-relevant flow-sensing scenarios using superficial or canal BNs. Implemented with specially developed algorithms, the ALLs successfully localized some underwater vibrating sources via hydrodynamic imaging, and demonstrated schooling capability.
