【摘要】 驻极体静电俘能器具有灵敏度高、无需外接电源、易于MEMS器件集成等优点。本文主要用ANSYS Multiphysics及Matlab/Simulink对单自由度双端固支梁驻极体静电俘能器进行理论建模。结合试验样机对俘能振动特性进行仿真分析及试验验证。结果显示理论模型、仿真分析及试验结果一致。更多还原

【Abstract】 Electret-based electrostatic energy harvester has the advantages of high sensitivity,no external power supply and easy integration of MEMS devices.In this paper,ANSYS Multiphysics and Matlab/Simulink are used to model electret-based electrostatic energy harvester of single-degree-of-freedom double-clamped beams.The simulation analysis and experimental verification of the vibration characteristics of the captive energy are carried out by using the experimental prototype.The results show that the theoretical model,simulation analysis and test results are consistent.更多还原
