title = "Design of mechanical sensing system based on PVDF piezoelectric sensor",
abstract = "A mechanical sensing system based on PVDF piezoelectric sensor was designed. Piezoelectric equation of PVDF was studied and simplified for data analysis. The algorithm of power frequency elimination was detailed studied. 4-times sampling was adopted during A/D transformation and the noise induced by 50Hz power frequency was minimized. Butterworth low-pass filter and trap filter was used for noise filtering. The measuring system consisted of PVDF sensor, charge amplifier, signal filter, A/D, MCU and LCD. The data acquisition and processing program was also written. Simulation and experiments proved the effective of this system.",
