Abstract
The invention discloses a method and apparatus to control the shaping change of Shape-Memory-Alloy (SMA). The piece-wised current drain control device is designed to independently deliver current to stimulate sectional SMA but not the entire one. The invention is also successfully implemented on an automatic light sensitive aperture control device to simulate the light response of a pupil. The control technique can extend the application potential of SMA toward precise actuation, aeronautical applications, surgical tools, or biomedical applications such as artificial organ or muscles.
