P-878 DuraAct Power Patch Transducer
High Efficiency and Robust
- Useable as actuator, sensor or energy generator
- Low voltages to 120 V
- Compact design
- Individual solutions

Patch transducer
Functionality as actuator and sensor component. Nominal operating voltages of -20 to 120 V. Power generation for self-sufficient systems possible up to the milliwatt range. Can also be applied to curved surfaces.
In longitudinal direction, the DuraAct Power uses the high-efficiency d33 effect.
Robust, inexpensive design
Laminated structure consisting of PICMA® multilayer piezo element, 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.
Customized versions and other specifications on request
- Flexible choice of size
- Variable design of the electrical connections
- Combined actuator/sensor applications, even with several active piezoceramic layers
- Arrays
Application fields
Industry and research. Can also be applied to curved surfaces or used for integration in structures. For adaptive systems, energy harvesting, structural health monitoring.
