They are superior to conventional multilayer actuators in industrial applications and high-endurance situations, where they show substantially longer lifetimes both in static and dynamic operation. New Production Process, Optimized PZT Ceramics PICMA™ piezo actuators are made from a ceramic material in which the piezoceramic properties such as stiffness, capacitance, displacement, temperature stability, leakage current and lifetime are optimally combined. The actuators' monolithic design and special electrode structure was made possible by advances in production technology. This development is just one reflection of the more than 30 years experience of PI Ceramic with thousands of industrial PZT applications. Increased Lifetime through Humidity Resistance 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. High-Level Dynamic Performance-Very Wide Temperature Range The high Curie temperature of 320°C gives PICMA™ actuators a usable temperature range extending up to 150 °C. This means that they can be operated in hotter environments, or they can be driven harder in dynamic operation (with conventional multilayer actuators, heat generation -which is proportional to operating frequency - either limits the operating frequency or duty cycle in dynamic operation, or makes ungainly cooling provisions necessary). 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) Ideal for Closed-Loop Operation The ceramic surface of the actuators is extremely well suited for use with resistive or optical fiber strain gauge sensors. Such sensors can be easily applied to the actuator surface and exhibit significantly higher stability and linearity than with conventional polymer-insulated actuators. Amplifiers, Drivers & Controllers PI offers a wide range of control electronics for piezo actuators from low-power drivers to multichannel, closed-loop, digital controllers. Of course, PI also designs custom amplifiers and controllers. Precision Mechanics and Mechanical Engineering NanoPositioning / High-Speed Switching Active and Adaptive Optics Vibration cancellation Pneumatic & Hydraulic Valves Metrology / Interferometry Life Sciences, Medicine and Biology PICMA™ piezo actuators are currently available with cross-sections of 2x3, 3x3, 5x5 and 10x10 mm². PICMA™ dimensions, in mm PICMA™ piezo actuators (bottom curve) compared with conventional multilayer actuators with polymer insulation (top curve). PICMA™ Actuators are not affected by the high-humidity test conditions. Conventional piezo actuators exhibit increased leakage current after only a few hours. Leakage current is an indication of insulation quality and expected lifetime. Test conditions: U = 100 VDC ; T = 25 °C; Relative Humidity = 70% The displacement of PICMA™ actuators exhibits very low temperature dependence. This, in combination with their low heat generation, makes PICMA™ actuators optimal for dynamic operation. (Operating frequency f = 200 Hz) PICMA™ actuators are also available with 100 mm leads (order number extension .x1). Shown here is the 15 µm P-885.51 (battery for size comparsion). PICMA™ actuator with optional rounded top piece for decoupling lateral forces and optional wire leads.
