Multilayer Piezo Actuator

Doon Ceratronics offers a multilayer piezo actuator developed by Noliac. The company has developed a range of ground-breaking products based upon more than ten years of R&D and innovation in multilayer piezoelectric ceramics. Noliac?s pioneering advances in multilayer piezoelectric technology enable much better performance and greater design flexibility than any other solution available in the market today. The company provides a wide range of standard linear actuators, bending actuators, generators and sensors, as well as providing endless possibilities for custom solutions to meet the exact specifications of customers? applications. The following standard component categories are currently available: ceramic multilayer actuators (CMA) single and stacked. Ceramic multilayer actuators (CMA) are co-fired multilayer ceramics typically with a height up to 2-3 mm and with up to 100 ceramic layers. The purpose of the stacking is to obtain more displacement than can be achieved by a single actuator. Ceramic multilayer actuators can be made very small, e.g., 1~1~0.2 mm, and can be designed in a variety of geometries, such as squares, rings and discs. The most common actuator geometry is a square with typical performance range up to 5??m stroke and up to 4,000 N blocking force. Noliac has also developed ring or disc shape actuators with typical performances range up to 5??m stroke and up to more than 30,000 N blocking force. Multilayer actuators are used in numerous applications within, e.g., piezo valve, piezo motor, optics, optical switch, telecommunication, instrumentation, automotive, nano-positioning, etc.
