P-876 DuraAct™ patch transducers combine the functionality of piezoceramic materials as sensors and actuators as well as for electrical charge generation and storage. Used as a bender actuator, they allow high deflection with high force and precision. Other possible operation modes of DuraAct™ transducers are as high-dynamics sensor (e.g. for structural health monitoring) or for energy harvesting.
Integration into Adaptive Systems
With their compact design, DuraAct™ transducers can be applied to structure areas where deformations are to be generated or detected. For this purpose the transducers can be affixed to the surface of structures or they can be integrated as structural elements. Whole areas are monitored effectively by applying an array of several DuraAct™ on a surface.
DuraAct™patch transducers are ideally suited for active and adaptive systems. Embedded in a servo-control loop, vibrations can be reduced and structures can be controlled in the nanometer range.
Robust and Cost-Effective Design for Industrial Applications
The laminated design consisting of a piezoceramic plate and polymers provides a mechanically preloaded and electrically insulated device for easy handling. P-876 patch transducers feature a rugged design with the mechanical stability of a structural material.
Energy Harvesting: Self-Sustaining Systems in a Small Package
Another operation mode of DuraAct™ patch transducers is the application as energy harvester. The transformation of mechanical vibrations up to some kilohertz may yield electrical power in the milliwatt range. This power supplies miniature electronic devices like LEDs, sensors or even transmitters for remote data control.
