Micromachined Gyroscope For Angle Measurements

技術優勢: 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

技術應用: Avionics systems Navigational equipment (ships, submarines, aircraft, spacecraft) Defense-specific applications

*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.
