Physik Instrumente’s P-876 flexible piezo transducer can be used for sensing and actuation.
- Compact design
- Individual solutions
- Useable as an actuator, sensor, or energy generator
- Inexpensive
- Minimum bending radii of down to 12 mm
Path Transducer
Functions as actuator and sensor component. Depending on the active layer height, the nominal operating voltage ranges from 100 to 1000 V. Up to milliwatts of power can be generated for self-sufficient systems. It can also be used on curved surfaces.
Robust, Inexpensive Design
A piezoceramic plate, electrodes, and polymer materials are laminated together to form this structure. It is made using a bubble-free injection process. The polymer layer acts as electrical insulation and mechanical preload, allowing the DuraAct to bend.
Customized Versions and Other Specifications on Request
- Combined actuator/sensor applications, even with several piezoceramic layers
- Multilayer piezo elements
- Arrays
- Flexible choice of size
- Flexible choice of thickness and therefore bending ability
- Flexible choice of piezoceramic material
- Variable design of the electrical connections
Application Fields
Applications include industry and research. It can also be applied to curved surfaces and structures, as well as monitoring structural health, adaptive systems, and energy harvesting.
