38*15*5 Piezoelectric Ceramic Element Ring Piezoelectric Ceramic For Ultrasonic Vibration Trasnducer

Piezoelectric ceramic sheets are devices that can generate electrical energy under pressure. When people speak to piezoelectric ceramic sheets, sound waves transmit a pressure to the piezoelectric ceramic sheets, thereby obtaining a certain amount of electrical energy; After converting sound into electrical energy and amplifying it, it can be used to control the device. The commonly used piezoelectric ceramic sheets are shown in Figure a. It is made of silver electrodes on both sides of piezoelectric ceramic sheets, polarized and aged, and then bonded with brass (or stainless steel) sheets using epoxy resin to form a sound emitting device.
