Modelling analysis for design of microshutters with new electrode configuration
Sensors and Actuators A: Physical(2022)
Abstract
The Next Generation Microshutter Array (NGMSA) is an all-electrostatic actuated, programmable light transmission device used for multi-object spectroscopy. The latest NGMSA is designed to operate by applying a voltage difference between the shutter blade electrode and a single back wall electrode. We investigate the effects of different wall electrode configurations and present a bi-electrode design that allows reliable shutter actuation at a voltage difference of 70V.
