近年来，人型机器人在太空等恶劣环境条件下的医疗福利和工业应用领域备受关注。为了实现这种机器人，需要开发具有与人类手指一样出色的功能的致动器。据了解，储氢合金在氢化时表现出10-30%的显着体积变化，比热膨胀引起的体积变化大几十倍。由于氢化驱动的致动器的驱动力是基于相变的，因此可以期望致动器表现出高功率。在本工作中，制备了具有与铜箔粘合的片状钯基储氢合金箔的弯曲模块，并研究了其弯曲行为。
In recent years, human-type robots attract much attention in the field of medical welfare and industrial applications under severe environmental conditions, such as in space. For the realization of such robots, the development of an actuator having superior functions as human fingers is required. It is known that hydrogen storage alloys exhibit a significant volume change of 10–30% on hydrogenation, which is several tens times greater than that caused by thermal expansion. Since the driving force of an actuator driven by hydrogenation is based on phase transformation, the actuator can be expected to show high power. In the present work, a bending module having a sheet form of palladium-base hydrogen storage alloy foils bond with a copper foil was prepared and its bending behaviors were investigated.
