Abstract
Shape Memory Polymer (SMP) is suitable for MENS actuator because it is light, and the amount of the transformation is large. SMP is the glass transition temperature (Tg) to recover the shape of the molding over time, Tg below to hold the shape. This shape-memory because unidirectional, there is a need to devise a structure. Indicate that the following structure and operating principle, in the film and forming one side of the SMP board will give the deflection shape memory. Similarly, the opposite different Tg of the SMP in terms of shape memory before giving a deflection to forming the. reverse, thickness 0.1mm, length 30mm, width 3mm, PET material was measured using the relationship between temperature and displacement of the beam, less temperature (Tg1) of about 100μm tip caused by the deflection of beams, high temperature (Tg2) is offset by the deflection, it was confirmed that work above and below the temperature constant
