Piezo Film
Piezoelectric Film 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. It makes a highly reliable, low-cost vibration sensor, accelerometer or dynamic switch element. Piezo Film is also ideally suited for high fidelity transducers operating throughout the high audio (>1kHz) and ultrasonic (up to 100MHz) ranges.
Learn more about how Piezo Film works or download the Piezo FAQs and the Piezo Product Guide and Price List.
Piezo film elements are offered in four variations: silver ink screen printed electrodes, lamination for higher voltage output when bending, flexible leads and shielded sensors. Applications include dynamic strain gauges, vibration sensors for alarms, switches, speakers and contact microphones. Piezo film design kits are a good starting point to learn more about Piezo film sensors and their applications.

Measurement Specialties manufactures Piezo polymer into a coaxial cable format, where the Piezo polymer is the “dielectric” between the center core and the outer braid. Two versions of the Piezo cable are offered: copolymer and spiral wrapped PVDF. When the cable is compressed or stretched, a charge or voltage is generated proportional to the stress. Piezo cable is extremely rugged, and will stand up to heavy loads as with truck axle counting. Its linear format makes it ideal for monitoring large areas.
