Micromachined Gyroscope For Angle Measurements

Tech ID: 18591 / UC Case 1999-003-0

Abstract

Researchers at the University of California, Berkeley have developed a new micro-machined device which measures directly the angle of rotation, in contrast with any conventional micro-machined gyroscope that measures the rate of rotation. Integrated on a single silicon chip, this unique micro-gyroscope is based on inertial properties of elastic waves.

Applications

Avionics systems
Navigational equipment (ships, submarines, aircraft, spacecraft)
Defense-specific applications

Advantages

Reduced size, weight and energy consumption
Improved reliability and functionality
Suitability for low cost, high volume production
Sustains energy level and allows on-line compensation of manufacturing defects, thanks to a robust non linear feedback control architecture
Allows multi-directional vibrations and does NOT interfere with the inertial Coriolis force, contrary to conventional vibratory type gyroscopes
