摘　　要：研究了聚偏氟乙烯(PVDF)压电薄膜的电压输出特性。根据运动员训练的需要,设计了适合于运动员动态足底压力测量的PVDF压电薄膜传感器,提出了高阻电压放大器对传感器的输出信号进行采样及处理,组成了运动员足底压力动态测量系统。该系统能在运动员的运动过程中实时、稳定并可靠地输出其足底压力的动态信号,为运动员的姿态矫正提供了依据。The output voltage characteristics of PVDF piezoelectric film are studied in the paper. According to the needs of the athletes training, a new sensor based on the PVDF piezoelectric film is designed to measure the ath- letic dynamic plantar pressure. High-impedance voltage amplifier is used to sample and process the signal which out put from the sensor. The athletic plantar dynamic pressure measurement system is build up, able to output the dy- namic signal of the athletic plantar pressure in real-time and stable and reliable, which provides a basis for the cor- rect attitude for athletes.
