![Piezoelectric Materials: Advances in Science, Technology and Applications: Proceedings of the NATO Advanced Research Workshop, Predeal, Romania, 24-27 May, 1999 (Nato Science Partnership Subseries: 3)](http://monsterbookshop.co.uk/cdn/shop/products/9780792362135_5af4dfba-151e-4b02-91a4-c215fda3829b.jpg?v=1702363025&width=1445)
In the last few decades the applications of piezoelectrics to sensors have witnessed a dramatic acceleration and new devices and materials have been discovered. Some of the highlights include electrostrictive materials for positioners, relaxor-normal ferroelectric single crystals with very high electromechanical couplings for medical transducers, thin/thick PZT films for microelectromechanical systems, starting from a sophisticated chemical technology, and multilayer actuators fabricated by a cofiring technique. All will make a remarkable industrial impact in the 21st century.
