Trends in Electromechanical Transduction

JUL 01, 1998
The demand for more sophisticated sensors and actuators in industrial equipment and consumer products is behind today’s push for new transducer materials and geometries.
Ilene J. Busch‐Vishniac

In today’s world, it is nearly impossible to avoid contact with electromechanical sensors and actuators over the course of the day, although we rarely recognize them. They drive the keyless entry systems, the light switches that respond to sound or motion, the detectors in cars that determine whether seat belts are fastened and the sound‐receiving and sound‐generating parts of the telephone, to name just a few examples.
