In the framework of intelligent materials, actuators, sensors and control systems have been developed in an attempt to replicate the main functions performed by muscles, nerves and brain, respectively [1]. The actuators have been developed from various types of intelligent materials such as: piezoelectric, shape memory; electro and magnetostrictive and electro and magnetorheological materials that have the general ability to react to thermal, electric, chemical, wavelength or magnetic fluctuations [2]. Shape Memory Alloys (SMAs) can be used either as electric or as thermal actuators [3], which are able to develop very high power densities, with proper control of both non-linear motion and cooling process [4].
