Abstract

A SMA actuator fabricated in this paper generates the large force and it's structure is very simple. The SMA actuator was fabricated by small size with diameter of 9mm and length of 27mm and also it's actuations toward all the directions can be acquired because of three springs which was fabricated with diameter of 2.4mm and 28 turns. We showed into applicability to smart catheter by analysing accurately the dynamic characteristics such as heading angle, force, displacement.
