Abstract
We suggested the novel actuator mechanism to apply to wearable assistive system for the improvement of quality of life of the elderly or the people with disability using it. Characteristics of metal-hydride (MH) actuator is investigated in the novel actuating concept. The hydrogen equilibrium pressure increases when hydrogen is desorbed by heating a SMH alloys, whereas by cooling that alloys, the hydrogen equilibrium pressure decreases and hydrogen is absorbed. However, there are too long times in heat transfer mechanism to apply the assistive and rehabilitative device. In this study, 3 different SMH module were designed and characteristics of heat transfer in each SMH module were investigated based on the heat simulation.
