Abstract

In this paper, we proposes a bending actuator using shape memory alloy coil-type springs. By the heating of two shape memory alloy coil-type springs sequentially, the bending and stretching motion of the actuator is possible. We measure the bending angle and repeated bending motion with the various currents. Furthermore, we control the bending angle of the 1 directional bending actuator with sensors. The performance of the actuator has been characterized or the possible application for catheter.
