Paper Abstract

In this paper, a flexible Shape Memory Alloy (SMA) actuator based on Thermoelectric Module is presented. The proposed actuator is consist of a pre-shaped SMA wire at several located positions, and a two couples of Thermoelectric Modules (TEM), and some temperature sensors. This actuator is adopted the TEM as the driven mechanism, and it can drive the pre-shape SMA directly. Using this driven mode can directly control pre-location of the SMA actuator. Therefore the control flexibility of the actuator is greatly increased. This paper analyze of the differences and advantages between the TEM actuator and the traditional SMA actuators, and introduced the operational mechanism, structure and driven approach. The experimental results indicate that the actuator can make reciprocating motion smoothly and softly.
