Piezoelectric actuators are electromechanical transducers that convert electrical signals into mechanical displacement and are widely used as controlling or regulating devices in modern equipment. Unictron’s bending actuator is an important type of piezoelectric actuator which can produce bending movement with designated force and displacement. Actuators with either unimorph or bimorph design are available per your request. Our bending actuators can generate consistent bending force output and also show excellent mechanical properties, reliability and durability.
Unictron is the major piezoceramic elements provider in Taiwan. Our engineering teams have been working in the piezo ceramic industry for more than 25 years. We have a sound background in materials formulations and ceramic processing technologies. With advanced characterization and manufacturing facilities, we are able to develop and mass produce various dimensions and specifications of piezo bending actuators to meet your requirements.
Piezoceramic bending actuators are suitable for needle control of knitting machines in the textile industry. Piezoceramic needle selectors are widely used in sock machines, hosiery machines, seamless knitting machines, circular knitting machines, etc. Bending actuators can also be used in the Braille display as well as the controlling mechanism of switches and valves.
