PRELIMINARY GALFENOL VIBRATORY GYRO-SENSOR DESIGN

摘要

This paper presents a prototype micro-gyro sensor design that employs the new magnetostrictive alloy GalFeNOL for transduction of Coriolis induced forces into an electrical output. The concept takes advantage of the principles employed in vibratory gyro sensors and the ductile attributes of GalFeNOL to target high sensitivity and shock tolerance in a miniature gyro sensor. In this study, preliminary test results are presented as concept verification with a meso-scale tuning fork vibratory gyro sensor.
