Abstract: Actuators using shape memory alloy (SMA) are applied widely in the fields of industry and medical. The SMA actuator using “resistance feedback control method” can control and retain positioning at any positions without using sensor devices. Since the resistance feedback control method requires a high electrical resistor of SMA element, the low power actuator using the thin line SMA is manufactured. In this study, we produced an actuator using SMA mesh element which is made of the thin line SMA and thin line aluminum with alumite film. This SMA mesh element is not only applicable to the SMA actuator using resistance feedback control method, but also enables increase of the output of the SMA actuator. The output power and control distance of the manufactured SMA mesh actuator are 2.2kgf and 6mm, respectively. This performance data is a half of the targeted value. It is thought that the cause of the performance decrement of the actuator is caused by the insufficient fixation of the mesh to the actuator.
