|The motion is based on crystalline effects and so there are no rotating parts, neither is there any friction; piezo actuators are therefore practically maintenance-free and non-wearing. To keep the operating voltages low, the individual layers in the so-called multilayer actuators are very thin. They are manufactured using co-fired technology which guarantees maximum reliability. The actuators are electrically insulated in a way which is humidity resistant and are used in medical engineering, e.g. in dosing applications, pumps and valves.|
