基于双稳态的振动能量收集系统的设计
Design of Vibration Energy Harvester Based on Bistability
摘要
Abstract
An energy harvester was designed by permanent magnets,a cantilever beam,piezoelec-tric material and so on,and the influence factors were studied experimentally and theoretically herein. The conclusion is made that the system has a bistable behavior under the suitable magnetic distance, which broadens the range of frequency response and increases the response amplitude,and the nonlin-ear bistable system has a higher efficiency of energy harvesting than that of a linear system under the suitable excitation amplitude and excitation frequency.关键词
