Piezo film sensor components

Piezo cable, film sheets and film elements provide the ability for measuring stress, strain and vibration to support a number of novel applications.

A range of piezo thin film sensors from Measurement Specialties is now being held by UK supplier, Variohm EuroSensor. The films offer unique transducer capabilities, producing voltage in proportion to compressive or tensile mechanical stress and strain. They are compact and reliable and can be used as low-cost dynamic strain gauges, vibration sensors, accelerometers or dynamic switch elements. Piezo Film is also ideally suited for high fidelity transducers operating throughout the high audio (>1kHz) and ultrasonic (up to 100MHz) ranges.

The range includes piezo cable, piezo film sheets and piezo film elements in addition to components such as piezo switches and ultrasonic sensors. Application areas for these materials and components are as diverse as the products. Piezo cable for instance can be a very effective medium for cost effective road vehicle axle counting systems where its compressive qualities – where voltage is generated proportional to the stress – can help determine both the number and load size of vehicles sampled. Piezo film finds uses in simple loudspeakers for instruments or as anti-tamper film for packaging. Piezo film elements are sub-components that can be used in dynamic strain gauges or as vibration sensors for alarms whilst piezoelectric ultrasound transmitters and receivers offer unique advantages for two-dimensional positioning applications such as digitising pens, object detectors or distance measurement devices.

The Measurement Specialties piezo film sensor range is also supported with a range of piezoelectric laboratory amplifiers to aid development.
