2913 Research on Ultra Sonic Heating for Manipulator made of Shape Memory Polymer
Details
In the present paper, a pipe type micro robot made by shape memory polymer is proposed and developed. The shape memory polymer has the big rebound warp limit more than the glass metastasis temperature compared with a general material of almost 100 percent. Moreover, the shape memory polymer can be about 100 times different the degree of elasticity before and behind the glass metastasis temperature, and its structure body become hard more than the glass metastasis temperature, and become rubbery softly below the glass metastasis temperature. By use of this feature, the pipe type micro robot, that is, micro manipulator can bend at the joint by heating actuation. The heating method by use of ultrasonic wave with MHz type is discussed and bending performance at the joint is confirmed in experiments.
