P-876 DuraAct™ patch transducers are piezocomposite transducers for adaptronics and commercial applications such as aerospace, smart structures, automotive, and machinery. The can also be used for energy harvesting and for structural health monitoring. DuraAct™ patch transducers offer the functionality of piezoceramic materials as sensors and actuators as well as for electrical charge generation and storage. Used as bender actuators, they allow high deflection of up to 0.8 mm with high force and high precision. Other possible operation modes of DuraAct™ transducers are as high-dynamics sensors.
Adaptronics
These patch transducers are ideally suited for active and adaptive systems. Embedded in a servo-control loop, vibrations of parts can be reduced and contours can be controlled in the nanometer range. A special Piezo Linear Amplifier is also offered. The E-413.D2 is a stand-alone, amplifier board and provides precision control for bipolar piezo shear and bender actuators both in static and dynamic operation.

Other possible operation modes of DuraActTM transducers are as high-dynamics sensors (e.g. for structural health monitoring) or for energy harvesting.
Integration into Adaptive Systems
With their compact design, DuraActTM 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 surfaces of structures or integrated as structural elements themselves. Whole areas can be monitored effectively by applying an array of several modules to a surface.
DuraActTM patch transducers are ideally suited for active and adaptive systems. Embedded in a servo-control loop, they can reduce vibrations and control structures in the nanometer range.
Robust and Cost-Effective Design for Industrial Applications
The laminated design with piezoceramic plate and polymers provide 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
One possible application of DuraActTM patch transducers is in the field of energy harvesting. Transformation of mechanical vibrations of up to some kilohertz into the corresponding potential difference can yield electrical power in the milliwatt range. This power can supply miniature electronic devices like diodes, sensors or even radio transmitters for remote data control.
DuraActTM transducers can be offered in highly customized versions:
Flexible choice of dimensions Flexible choice of thickness and bending properties Flexible choice of piezo-ceramic materials and operating temperature Various electrical connection designs Combining sensor and actuator functions (multiple ceramic layers)
