ABSTRACT:
A piezoelectric flexural sensing structure having increased sensitivity and decreased noise, without sacrifice of the sensor bandwidth. The structure is made up of a proof mass, a beam with a base and optionally having castellated bonding surfaces and two <011> poled bonding mode PMN-PT crystal plates mounted on the beam.
