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 film is available in a variety of different sizes, thicknesses and metalization 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.

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.

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 digitizers, object detection, and distance measurement.

Measurement Specialties is the pioneer and world leader in offering accelerometers manufactured out of piezoelectric film.  Piezo film accelerometers are ideal for dynamic OEM vibration applications because they are low cost, highly sensitive and very reliable – and they require no external power source.  Applications include medical devices, appliances, alarms and security systems, industrial switches and even games.
