DuraAct Piezoelectric Transducers

Robust and Flexible Patch Transducers

DuraAct piezoelectric patch transducers are "Smart Materials" having both sensor and actuator characteristics. Therefore, the patch transducers can be used as sensors and actuators as well as to generate and store electrical charge. The patented laminated structure of piezo ceramic, electrodes and polymer exterior is electrically insulated and, at the same time, mechanically robust.

The piezo ceramic consists of one or several plates manufactured by pressing. Alternatively, multilayer piezo ceramics are integrated; they have a higher efficiency and require a considerably lower electrical voltage.

Bendable and Robust

High Efficiency and Robust

DuraAct piezoelectric transducers are produced in different shapes. Customized designs to match your application are also available. Whether special electronics or special geometries – on request, we will gladly offer you customized products.

Standard contacts for piezo actuators are 100 mm stranded wires or soldering points. For each piezo element, different wires acc. to the AWG standard are used. Please observe the soldering instructions for each product.

DuraAct patch transducers can be adapted individually to each application. This includes a free selection of dimensions and geometric shape. The height of the piezo ceramic determines the bending properties. Depending on the operating temperature, various piezoceramic materials can be used.

To monitor larger areas, several DuraAct transducers can be incorporated in one single laminate. Electrical contacting of the piezo ceramics is established jointly or individually. If a single DuraAct element is used both as actuator and sensor, the piezo ceramic can be built in several layers.

For sensor data processing, controlling the DuraAct actuator or for harvesting energy and structural health monitoring, electronic modules can be connected close to the transducer. Contact is established using solder pins or miniature plugs.
