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.
Piezo Cable
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.

Piezo film is available in a variety of different sizes, thicknesses, and metallization options for OEM manufacturing. Sheets can be fabricated into simple transducers or used at full size for applications such as speakers or security anti-tamper film.
Piezo Switches and Ultrasonic Sensors
Measurement Specialties has done pioneering work in the development of ultrasound sensing using Piezo film. Piezoelectric film ultrasound transmitters and receivers offer unique advantages for two-dimensional positioning applications such as digitizers, object detection and distance measurement
