AUBURN, Mass., Oct. 16, 2007 -- PI (Physik Instrumente) L.P. said its new P-876 series piezo composite patch transducers can be used as actuators, sensors, and as energy sources.
P-876 transducers are highly bendable piezo composite patch transducers tolerating bending radii as low as 20 mm (3/4 in.) They are manufactured by placing a piezoceramic foil between two conductive films, all embedded in a ductile composite-polymer structure. In this way, 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 lifetime well over 10+9 cycles. Wear and failure rates are low, as the solid-state actuators contain no moving parts, PI said.
P-876 patch transducers combine the well-known functionality of piezoceramic materials as high-precision, high-dynamics sensors and actuators. Other possible uses and commercial applications for the P-876 are: energy harvesting, energy storage, mechanical engineering, aerospace, aviation, automotive, civil engineering and in sporting goods. Used as bender actuators, they allow high deflection of up to 0.8 mm with high force and precision.
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 providing precision control for bipolar piezo shear and bender actuators both in static and dynamic operation.
