PI Ceramic | Advanced Piezo Materials, Custom PZT Material | Piezoceramic Materials, Leader in Piezo Technology. Piezoelectricity. A piezoelectric system (without contact tabs) Piezoelectricity is found in useful applications such as the production and detection of sound, generation of high voltages, electronic frequency generation, microbalances, and ultrafine focusing of optical assemblies. It is also the basis of a number of scientific instrumental techniques with atomic resolution, the scanning probe microscopies such as STM, AFM, MTA, SNOM, etc., and everyday uses such as acting as the ignition source for cigarette lighters and push-start propane barbecues.
History[edit] Discovery and early research[edit] The pyroelectric effect, by which a material generates an electric potential in response to a temperature change, was studied by Carl Linnaeus and Franz Aepinus in the mid-18th century. A piezoelectric disk generates a voltage when deformed (change in shape is greatly exaggerated) The Curies, however, did not predict the converse piezoelectric effect.
World War I and post-war[edit] World War II and post-war[edit] Piezoelectric ceramics-Weifang Jude Electronics Co.Ltd. Oxide Ceramics – Piezo-ceramics. Piezo-ceramic materials are categorized as functional ceramics. In sensors they make it possible to convert forces, pressures and accelerations into electrical signals, and in sonic and ultrasonic transducers and actuators they convert electric voltages into vibrations or deformations.
Piezo-ceramic materials are classified according to their chemical composition on the one hand, and by the specific application conditions on the other. CeramTec distinguishes between the following material categories: Materials for power transducers (ultrasonic applications) Materials for sensors (ultrasonic transmitters and receivers) Materials for actuators (precision positioning or injection systems) Materials for special applications Contacting of the metalized piezo-ceramics can be made using conductive adhesives, conductive rubbers, spring contacts or via soldering.
