Abstract:
A piezoelectric Micro-Electro-Mechanical Systems (MEMS) device comprising: a physical element; and a piezoelectric sensor element, with the physical element positioned in proximity to a moving portion of the piezoelectric sensor element, and with proximity of the physical element to the moving portion reducing a probability of breakage of the piezoelectric sensor element by limiting an excursion of the piezoelectric sensor element, relative to a probability of breakage of the piezoelectric sensor element in another piezoelectric MEMS device without the physical element.
