Piezo Composite Patch Transducer from PI
Piezo composite patch transducers.
Auburn, MA — PI (Physik Instrumente) L.P. is introducing the new P-876 line of piezo composite patch transducers are highly bendable piezo composite patch transducers tolerating bending radii as low as 20mm (3/4-in.) They are manufactured by placing a piezoceramic foil between two conductive films, all embedded in a ductile composite-polymer structure.

The brittle piezo-ceramic is mechanically prestressed and electrically insulated, which makes the transducers extremely robust. The rugged design ensures reliability, high resistance to damage and a long useful lifetime. Wear and failure rates are low, as the solid-state actuators contain no moving parts.

The patch transducers combine the well-known functionality of piezoceramic materials as high-precision, high-dynamic sensors and actuators. Other possible uses for P-876 are for energy harvesting and energy storage. Used as bender actuators, they allow high deflection of up to 0.8mm with high force and precision.

These patch transducers are especially 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 standalone amplifier board providing precision control for bipolar piezo shear and bender actuators both in static and dynamic operation.

Commercial applications of piezo composite patch transducers mechanical engineering, aerospace, aviation, automotive industry, civil engineering, and sporting goods.
