An original method for estimating the parameters of MEMS sensors is presented. It is based on the measurement of binary oscillations appearing at the system's output when a discrete-time relay feedback is used: the parameters of the system can then be deduced from the shape of these oscillations with a very good accuracy. This method is presented and demonstrated in the case of the identification of some cantilever micro-beams.
