PvdF Piezoelectric Film Based Force Measuring System
並列摘要
In this study, a force measuring system based on PVDF piezoelectric sensor was designed. Firstly, piezoelectric equation of PVDF was simplified for the following analysis. Secondly, circuits of charge amplifier and signal filter were designed. Noise induced by electronic components and 50 Hz power frequency were restrained heavily by 5^th-order Butterworth low-pass filter and 50 Hz double T trap filter. Finally, a measuring circuit board was made based on the above research, so as to construct measuring system and measure experiment. Measuring experiment proved the effective of this system.
