Micromachined Electric Field Mill Employing a Vertical Moving Shutter [PDF]
AbstractThis paper presents a new type of micromachined electric field mill (MEFM) for measuring dc electric fields. This MEFM employs thermal actuators for vertical movement of an electrically grounded shutter, to mill the amplitude of a dc electric field incident on underlying sense electrodes. It addresses the main drawbacks of existing MEFMs, which
