Abstract

Small form-factor MEMS devices and methods of using the devices. An exemplary MEMS device includes an ACM. Certain devices comprise nanometer scale sensing gaps in the out-of-plane direction to increase vibration sensitivity in a vacuum casing. Certain devices described herein provide a differential sensing mechanism. Accelerometer contact microphones having an operational bandwidth ranging from 0 Hz and 10,000 Hz are also disclosed. The vibration acceleration sensitivity of certain devices described herein is better 100 μg√Hz.
