Optomechanical reference accelerometer [PDF]
Metrologia, 2015 We present an optomechanical accelerometer with high dynamic range, high bandwidth and read-out noise levels below 8 ${\mu}$g/$\sqrt{\mathrm{Hz}}$. The straightforward assembly and low cost of our device make it a prime candidate for on-site reference ...

Electrostatic anti-spring-enhanced MEMS accelerometer with auto-tuning capability [PDF]
Microsystems & NanoengineeringThis study introduces a MEMS accelerometer equipped with an adaptive tuning system for an electrostatic anti-spring. As the input acceleration increases, the sensitivity of the adaptive MEMS accelerometer decreases to compensate for the measurement range.

Accelerometer Calibration Technique [PDF]
The Journal of the Acoustical Society of America, 1950 A technique is described for the dynamic calibration of accelerometers or other vibration-measuring instruments. For each calibration frequency the accelerometer is attached to a free-free bar driven electromagnetically at a known sinusoidal displacement. Displacement amplitudes are measured by means of strain gauges which are calibrated optically. The

On the design of a triaxial accelerometer [PDF]
Journal of Micromechanics and Microengineering, 1994 Up to now, mainly uniaxial accelerometers are described in most publications concerning this subject. However, triaxial accelerometers are needed in the biomedical field.

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.
