Piezo sensor

Piezoelectric fluoropolymer film, or Piezo Film for short, is an enabling transducer technology with unique capabilities. Piezo Film produces voltage in proportional to compressive or tensile mechanical stress or strain, making it an ideal dynamic strain gage.
Successful applications have been developed across a vast dynamic range from sensing nanostrains to measurement of explosive-level forces (Mbar). Piezo Film’s stress constant (voltage output per stress input) is about 10 times higher than other piezoelectric materials such as ceramics and quartz.
It makes a highly reliable vibration sensor, accelerometer and dynamic switch element.
