Problem-solving piezoelectrics: even now, piezoelectric phenomena-discovered by Pierre and Jacques Curie more than 120 years ago--remain something of a laboratory curiosity. Despite their distinguished service record in applications such as ultrasonic transducers, microphones, and accelerometers, piezoelectric products are just beginning to penetrate the wider marketplace, as the following examples attest.

Rotary torque transducer
While resistive strain gauges are the dominant technique for measuring static as well as dynamic strain, translation to non-stationary applications such as rotary shafts requires expensive slip rings or large low-frequency transformers.
Torqsense[TM] transducers present an alternative method for measuring strain, and therefore, torque. Developed by Sensor Technology Ltd., the patented transducer correlates velocity and attenuation of surface acoustic waves--SAW, also known as Rayleigh waves--with residual stresses in the surface ...
