P-876: Flexible Piezo Transducer for Sensing and Actuation

上海仪舶实验室自动化 25-01-23 13:06:35

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 andstructures, as well as monitoring structural health, adaptive systems, and energy harvesting.
