Piezo Film Sensors

The piezo film sensors provide durable vibration, accelerometer, or dynamic switch elements for a wide range of markets and applications.

Piezoelectric fluoropolymer film has unique capabilities and produces voltage or charge proportional to dynamic strain.

The film is suited for many different custom designs, configurations, and applications, including versatile coaxial cable used for everything from security to musical instrument amplification.
