  • Method of making a pressure sensor comprising a resonant beam structure
    Patent number: 6546804
    Abstract: A resonant microbeam pressure sensor is disclosed, comprising a microbeam suspended by a diaphragm at one or more points by suspension elements. Pressure applied to the diaphragm will cause the resonance frequency of the beam to shift. This shift is detectable and proportional to the pressure. The device is manufactured by surface micromachining.
    Type: Grant
