A butterfly vibration acceleration sensor with wide-range
small volume and high resonance frequency
aiming at the application requirements of fault diagnosis and safety monitoring.The specific dimensions of the sensitive structure are simulated and optimized based on the finite element analysis(FEA) software of COMSOL.The accelerometer sensitive structure is fabricated by the SOI wafer.Then the sensitive structure and the signal detecting circuit are integrated and encapsulated by the sensor package part.Finally
the main performance of the sensor are characterized including sensitivity
