Active vibration damping requires fast servo-control withīandwidth sufficient for close-coupling the generated force to the structural mass to be To operate a high-precision, high-dynamics positioner, a low-noise, broadband amplifier is required. Such custom products can be produced very efficiently, even in low quantities.ĭepending on the application, different demands are made on the electronics. The piezoelectric transducers can be designed to fit the application exactly, including even transducers with arrays of multiple ceramicĮlements. If the layers are wired separately, both sensor and actuator functionality can be used simultaneously. In an actuator, multiple layers result in higher force generation with the same operating voltage. For special applications, multilayer devices can be made available. Standard DuraAct™ patch transducers consist of one piezoceramic layer only. In addition to the range of standard designs, highly individualized structural shapes can be realized to meet different requirements of geometry, flexibility, stiffness or operating temperature. This means that DuraAct™ is also ideally suited for research and prototyping. The power, in the milliwatt range, can supply miniature electronics like LEDs, sensors or mini RF transmitters for remote data transfer.ĭuraAct™ piezoelectric transducer technology allows high flexibility in actuator design. Miniature Electric Generator for Autonomous SystemsĭuraAct™ patch transducers can extract electric power from mechanical vibrations of up to several kilohertz, thus acting as energy harvesting devices. Wear and failure rates are low, as the solid-state actuators contain no moving parts. The patch transducers are glued to the surface and can be used for various purposes.Įven in high-dynamics applications, the rugged design ensures reliability, high resistance to damage and a lifetime well over 10 9 cycles.

In this way, the brittle piezoceramic is mechanically prestressed and electrically insulated, which makes the transducers so robust that they can be applied on curved surfaces with a bending radius as low as 20 mm. Possible applications are in high-precision bender actuators, high-dynamics sensors or as power sources.ĭuraAct™ patch transducers are extremely compact units based on a thin piezoceramic foil between two conductive films, all embedded in a ductile composite-polymer structure. Piezoelectric components like the DuraAct™ patch transducer transform electrical to mechanical energy and vice versa. Piezo-Electric All-Rounder DuraAct™ Patch Tranducers

Applications article on different piezo transducers The magnitude of usable deflection depends strongly on the substrate properties, and extends into the millimeter range.ĭuraAct Transducers are available from PI Ceramic. The novel DuraAct™ patch transducers now offer a compact solution in this area.Īpplied directly to a substrate,or used as part of the structure itself, DuraAct™ patch tranducers can detect and produce vibrations or contour deformations at the source, inside the structure. With a long history as adaptive materials, piezoelectric transducers have been especially popular for the monitoring and active damping of high-frequency vibration. These systems are designed to detect and react to changes in their operating environment, like impact, pressure or bending forces. Structures using “smart materials” which integrate sensor and actuator functions are taking on growing importance. Piezoelectric Transducers are wide known for ultrasound generation and sensing, but they can also be used in self-correcting, adaptive systems in modern industrial applications and structural health monitoring.
