Research on Piezoceramics Actuators for Electronic Jacquard Applications

To reduce the size of equipment and enhance the response time, it is proposed to apply the piezoelectric ceramics to the electronic jacquard mechanism. After analyzing the piezoelectric ceramics needle-selected actuator theoretically, it is found that the tip displacement can be influenced by the applied voltage and its size under the quasi-static condition. Then a needle-selected mechanism was designed and tested on our home-made jacquard loom platform. The structure size of piezoelectric needle-selected actuator could be 50% less than the electromagnet one, meanwhile the action response speed is almost the same. That can be applied to design novel jacquard looms.
