Development of the MEMS Gravity Sensor (1)


Abstract
We developed a new MEMS gravity sensor with quartz crystals for experiments. We proposed an electric capacity change type sensor on which the drive electrode and the sensing electrode were prepared by making the piece of crystal of AT cut into cantilever structure as a structure of a sensor. We estimated the accuracy of the gravity sensor at about several-mgal, as a result of evaluation tests using the new MEMS gravity sensor.
