PVDF Piezoelectric Film Accelerometer for Low Frequency and Ultra-Low Frequency

Abstract:

Article Preview

The measurement of low and ultra-low frequency vibration has always been a very difficult problem. In this paper, a new structure is designed and a new type of low and ultra-low frequency accelerometer is developed by using a sensitive element PVDF. A new type of sensor structure and working principle are discussed and mathematical model and characterize are analyzed in this paper. The result confirmed that this design method can improve sensitivity, precision and performance of the sensor, overcome the acceleration interference of other direction in the vertical axis upwards, and improve the unilateralism and stability of the sensor.
