An integrated view of applications of electret technology in energy and health sectors

Electrets are truly a low energy device. Use of electrets; in electronic devices such as sensors, actuators and transducers save considerable energy. Electret integrated devices and smart materials are developing in hybrid form with silicon as next generation microelectromechanical systems. Recent advances in electret technology offer promise to serve mankind through medical prosthesis and by performing other biological functions. In this article, we present an integrated view of electret applications in energy and health sectors.
