PVDF压电薄膜传感器及其应用

PVDF Piezoelectric Film Sensor and Its Application

聚偏二氟乙烯(PVDF)压电薄膜传感器频响范围大、具有热电效应等的特性,应用潜力很大。在智能系统中用作传感器和作动器,在振动检测方面主要应用于音乐拾音、机器状态监测、轴承磨损、风扇气流和绳带断裂等,在加速度检测中作加速度计,在无损检测(NDT)中以传感器阵列的形式出现,还可用于人体运动、体育计分,人体健康、开关、打印头,乐器、麦克风,声纳,售货等的监测。

Polyvinylidence fluoride (PVDF) piezoelectric film sensor has a larger range of frequency response and characteristics of pyrolelectic effect, and extensive foreground of application. It is used as sensor in application of intelligent system, and it is mostly applied in vibration detection such as music pickup, machine state, bearing abrasion, airflow of fan and cordage rupture etc. In acceleration detection, it is used as acceleration meter, and used as sensors array in Non Destructive Testing (NDT). It also is adapted to monitor physical score, print element, musical instrument, microphone, sonar, sell goods and so on.
