Applications for piezoelectricity

Piezo Institute research into piezoelectric materials and devices is applied to the design of new and improved devices, and in critical industries such as healthcare and transport.

Devices which use piezoelectric technology include:

• Sensors to measure force, motion, acceleration, pressure and temperature

• Sensors to detect radiation (pyroelectric security surveillance devices) or chemical and biological elements

• Transducers for medical imaging, blood flow measurements, non-destructive evaluation and testing, industrial flow meters, underwater acoustics - sonar, airborne acoustics, filters and resonators for telecommunications including mobile phones

• Active devices such as actuators, micro-motors and micro-pumps

• Energy harvesting – the production of energy from motion

• A new generation of hearing aids

• Fuel injectors for diesel engines

• Ink jet printer heads

• High dielectric constant capacitors

• Stereo tweeters, buzzers, gas ignitors

• PTC sensors and switches

• Solid state ultrasonic motors

• Electro-optic light valves

• Thin-film capacitors

• Ferroelectric thin-film memories – FRAM

• Integrated MEMS devices – such as airbag sensors, accelerometers, force sensors etc.
