Abstract
Because of its high quality and highly stable mechanical
properties, quartz crystal is a well suited material for piezoelectric
vibrating inertial sensors. However, a new piezoelectric quartz-homeotypic
crystal, gallium orthophosphate (GaPO4) seems today a very promising
material for new generation of vibrating sensors. This paper gives the basic
relations between material properties and sensors performances, and the
expected improvements from using GaPO4for vibrating sensors are
discussed.
