Tunable MEMS cantilever resonators electrothermally actuated and piezoelectrically sensed
Electrically tunable MEMS cantilever resonators are presented. Electrothermal actuator and piezoelectric sensor are integrated on top of cantilever. Two-port measurements of transmission frequency response in air are performed. Device with shorter beam length shows a wider tuning range. Origin of resonant frequency change induced by tuning DC voltage is investigated.
