CeramTec UK Limited products

Piezoceramic actuators utilize the piezoelectric effect: A piezoceramic PZT material expands in the direction of the electrical field when voltage is applied to it. A piezoelectric actuator offers interesting solutions for micro-positioning, valve control, vibration damping and sound generation.

Piezo-ceramic multilayer actuators must be effectively protected against moisture to ensure reliable and lasting operation. Conventional polymer or ceramic coatings can only offer this to a certain degree. Tests have shown that leakage current greater than 1 mA already occurs here within a few seconds. CeramTec has an answer to this problem: Hermetically sealed actuators with active moisture suppression. No other company in the world offers this solution.
