Abstract

The new structure of in-plane high-g MEMS sensor for 10,000-150,000g has been designed in our paper, and it was packaged in dimensions of 17.5mm×12mm×4.5mm. In our experiments, the sensitivity reach to 0.335uv/g by the Hopkinson bar system and it also is in quick respose to the frequence. Meanwhile, the results show that all acceleration-time pulses are in very close agreement for acceleration amplitudes to about 150000g. It is a new way to monolithically integral triaxial piezoresistive high-g accelerometer in the future.
