Optomechanical Accelerometers for Geodesy
Remote Sensing, 2022 We present a novel optomechanical inertial sensor for low-frequency applications and corresponding acceleration measurements. This sensor has a resonant frequency of 4.715 (1) Hz, a mechanical quality factor of 4.76(3) × 105, a test mass of 2.6 g, and a projected noise floor of approximately 5 × 10−11 ms−2/Hz at 1 Hz.

A two degrees of freedom comb capacitive-type accelerometer with low cross-axis sensitivity
Journal of Mechanical Engineering and Sciences, 2019 In this paper, we report on a SOI-based comb capacitive-type accelerometer that senses acceleration in two lateral directions. The structure of the accelerometer was designed using a proof mass connected by four folded-beam springs, which are compliant ...
