What are Piezoelectric Ceramics? / Piezoelectric Ceramic Materials
A piezoelectric ceramic is an electronic component incorporated in various home appliances or industrial products.
Ceramics are also referred to as pottery, and are made by sintering powdered material, like tea cups. Manufacturing of those used as precision electronic components begins with uniform mixing of raw materials; then they are sintered in a furnace where temperatures are strictly controlled, and are finally provided with electrical characteristics.
Among various ceramics, those referred to as piezoelectric ceramics produce electrical energy when force is applied to them (piezoelectric effect), and inversely produce force when electrical energy is applied to them (inverse piezoelectric effect).
Since applying electricity to piezoelectric ceramics causes them to expand and contract (vibrate), they are used in a variety of areas, such as ultrasonic wave generating equipment of glasses cleaning machines, esthetic equipment including facial massagers, transmitters and receivers of fish detectors and sonars, and medial probes.
Also, the use of the piezoelectric effect and the inverse piezoelectric effect allows generation of large voltage from small voltage; therefore, piezoelectric ceramics are widely used in inverters for backlight of laptop computers, LCD TVs, etc., OA (office automation) equipment such as copy machines and fax machines, and negative ion generators of common home appliances.
