These multilayer piezoelectric components are manufactured from ceramic layers of only about 25 µm thickness. They feature internal silver-palladium electrodes and ceramic insulation applied in a co-firing process. The bender have two outer active areas and one central electrode network dividing the actuator in two segments of equal capacitance, similar to a classical parallel bimorph. Advantages PICMA™ Bender piezo actuators offer several advantages over classic bimorph components manufactured by gluing together two ceramic plates (0.1 to 1 mm thick): faster response time and higher stiffness. The main advantage, however, is the drastically reduced (by a factor of 3 to 10) operating voltage of 60 V only. The reduced voltage allows smaller drive electronics and new applications, such as in medical equipment. Additionally these devices offer an improved humidity resistance due to the 100 % ceramic insulation. Long Lifetime and High Performance-Ideal for Dynamic Operation PICMA™ Bender actuators are superior to conventional actuators in high-endurance situations. They show substantially longer lifetimes both in static and dynamic operation, even in harsh environments. The monolithic, ceramic-insulated design makes polymer-film insulation unnecessary. Diffusion of water molecules into the insulation layer, the major cause of dielectric breakdown, is greatly reduced by the use of cofired, outer ceramic insulation. The high Curie temperature of 320 °C gives PICMA™ actuators a usable temperature range extending up to 150 °C, well above the 80 °C limit of conventional multilayer actuators. At the low end, operation down to a few kelvin is possible (with some reduction in performance specifications). Optimum UHV Compatibility-Minimal Outgassing The lack of polymer insulation and the high Curie temperature make for optimal ultra-high-vacuum compatibility (no measurable outgassing / high bakeout temperatures, up to 150 °C). Amplifiers, Drivers & Controllers PI offers a wide range of standard amplifiers and controllers for piezo actuators. The E-650.00 and E-650.OE drivers were specifically designed to operate PICMA™ Bender actuators. For closed-loop positioning applications, a variety of analog and digital controllers are available. Of course, PI also designs custom amplifiers and controllers.
