Development of Artificial Muscle for Rehabilitation from SMA CellStructures with High Stretch Properties and High Generative Force

本研究的目的在于开发具有轻量化、弹性化、静音化的形状记忆合金（SMA）人工肌肉，以供复健器材使用。特别是，通过将SMA线加工成单元结构，轻质人造肌肉被控制为具有高拉伸性能和由温度变化产生的高生成力。对加工后的形状记忆合金丝进行了有限元分析和实验研究。因此，根据用途的最佳人工肌肉的设计的可行性，可以通过控制的几何形状和参数的SMA线和细胞结构的构造从多个线。

The purpose of this research is the development of artificial muscles with the lightweight, flexibility, and silence for rehabilitation devices from shape memory alloys (SMA). Especially, by the processing of SMA wires into cell structures, the lightweight artificial muscles are controlled with high stretch property and the high generative force by temperature change. The FEM analysis and experiments for processed SMA wires were conducted. As a result, the feasibility of designing of optimal artificial muscle depending on the usage could be shown by control of the geometrical shapes and parameters of SMA wires and construction of cell structures from multiple wires.
