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.
