When a voltage is applied, the DuraAct patch transducer contracts laterally.

DuraAct transducer design principle

DuraAct patch transducers can be manufactured in various shapes.

When arranged in an array, DuraAct patch transducers allow, for example, the reliable monitoring of larger areas.

Electronic modules for sensor data processing, controlling the DuraAct actuator or harvesting energy can be connected close to the transducer.

Patch transducer

Functionality as actuator and sensor component. Nominal operating voltage from 100 up to 1000 V, depending on the active layer height. Power generation for self-sufficient systems possible up to the milliwatt range. Can also be applied to curved surfaces.

Robust, inexpensive design

Laminated structure consisting of a piezoceramic plate, electrodes and polymer materials. Manufactured with bubble-free injection method. The polymer coating simultaneously serves as electrical insulation and as mechanical preload, which makes the DuraAct bendable.
