Insect-inspired drive strategy substantially improves the performance of a piezo motor

摘要: Abstract Bioinspiration has been a driving force behind the design of various solid-state actuators. While in nature structure an animal and control mechanisms have co-evolved perform best when used together, biologically-inspired actuators often employ oversimplified technical drive solutions. The piezo motor discussed this work is example such device. It consists four leg-like elements which need to interact with ceramic bar stable way. This presents novel bioinspired mechanism for motor. Specifically, architectural mapping between model walking insects proposed. In insect-inspired strategy, all piezoelectric legs are allowed be driven independently not pairs as opposed classical strategy. Based on physical dynamics, it shown that approach substantially improves performance terms its generating capabilities well maximal velocity. Furthermore, described by moderate number intuitive parameters produces variety velocity-dependent gaits known from research animals.
