Method and apparatus for using shuttered windows in a micro-electro-mechanical system

摘要

A windowed shutter (32) on a micro-electro-mechanical system improves output current of a non-contacting electrostatic voltmeter (v). The output current is increased by increasing the area modulated by the micro-electro-mechanical shutter system and by increasing the speed of that modulation. The increase in the area modulated by the windowed shutter is in direct proportion to the number of windows (34) used. Moreover, the speed of the modulation is increased by increasing the resonant frequency of the system. Less shutter mass increases the frequency thus increasing shutter movement over time. <IMAGE>
