Surface-micromachined resonant accelerometer [PDF]
Proceedings of International Solid State Sensors and Actuators Conference (Transducers '97), 2002 This paper discusses the design and testing of a resonant accelerometer developed for integrated surface-micromachining processes. First- and second-generation designs are presented. The sensors use leverage mechanisms to transfer force from a proof mass to double-ended tuning fork (DETF) resonators used as force transducers.
