Dynamic control of high-voltage actuator arrays by light-pattern projection on photoconductive switches

Herbert Shea, Amir Firouzeh, Vesna Bacheva, Edouard Franck Vincent Gustave Leroy, Aiste Balciunaite

The ability to control high-voltage actuator arrays relies, to date, on expensive microelectronic processes or on individual wiring of each actuator to a single off-chip high-voltage switch. Here we present an alternative approach that uses on-chip photoco ...
