  • High sensitivity, low noise piezoelectric flexural sensing structure
    Publication number: 20070119259
    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 bending mode relaxor piezoelectric crystal plates mounted on the beam.
    Type: Application
