SISTEMA BISTABILE AD ELETTRETI |
摘要 |
<p>The invention relates to bistable systems using electrets. The invention provides a three-electrode system in which the movement of the moving armature is obtained by means of biasing voltages applied to the fixed electrodes. A switching voltage applied between the moving electrode and one of the fixed electrodes releases the electrostatic holding forces generated by the electrets.</p> |
