Enhanced water flow sensing performance based on multi-ciliated structure of ionic polymer–metal composite

Ionic polymer–metal composite (IPMC) is a promising candidate for underwater sensing due to the merits of rapid response, flexibility, miniaturization, and self-powered nature. The high sensitivity sensor vital robots. Inspired by lateral line cilia fish, new water flow system based on multi-ciliated structure IPMC presented improve sensor. As illustrated experiments oscillatory flow, detection range reached 3.83 times increased about 39%, respectively, compared with that single In addition, an array composed systems IPMCs was successfully applied location vibrating dipole, while velocity prediction moving objects also realized minimum average error rate 1.70%. proposed in this paper be effective supplement traditional methods.
