Claim Text:
1. A method comprising: exciting a micro electromechanical systems (MEMS) sensor, via an electrical impulse, to cause a flexure of the MEMS sensor to vibrate and ring down; measuring a mechanical response of the MEMS sensor resulting from excitation of the MEMS sensor, as a voltage corresponding to vibration and the ring down of the flexure over time; determining a parameter of the MEMS sensor based on the response of the MEMS sensor that has been measured, by fitting a damped sinusoidal function corresponding to the vibration and the ring down over time to determine a resonant frequency and a Q value of the flexure; and, calibrating the MEMS sensor based on the parameter of the MEMS sensor that has been determined.
