In the 1950s, barium titanate was the first piezoelectric ceramic material to be adopted, mainly for use as ultrasonic transducer elements in fish finders. By the late 1950s, ...

For the first time, researchers at the Indian institute of Science (IISc) have designed a ceramic material capable of achieving an electrostrain value of 1.3 percent—the highest for a ceramic to ...

An unusual application of a piezoelectric transducer serves as an oscillator and drives a white LED (Figure 1). The piezoelectric diaphragm, or bender plate, comprises a piezoelectric ceramic plate, ...
