Individual solutions

P-878.A1, dimensions in mm

The DuraAct Power multilayer patch transducers use the longitudinal or d33 effect, which describes an elongation parallel to the electric field E and the polarization direction P of the piezo actuator. The d33 piezoelectric charge coefficients for longitudinal displacement are considerably higher than the d31 coefficients for transversal displacement, used by all-ceramic patch transducers (Source: Wierach, DLR).

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.

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

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.

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.
