Abstract

Rehabilitation systems and assistive technology devices for people with motor disabilities caused by stroke or the aging process require a human-friendly actuator that is soft, compact, slow, noiseless, and environmentally benign. In order to realize these kinds of actuators, we designed a soft metal hydride (MH) actuator using a copper-coated LaNi5 alloy and a laminate film bellows. For the purpose of this study, we selected a suitable LaNi5 alloy and developed a soft and light end-effector for the soft MH actuator. As a result of experimental tests, the LaNi5 alloy that has a low plateau pressure at room temperature performs well for the MH actuator. Moreover, the end-effector applied to the soft bellows made of an aluminum laminate film is 20 times lighter and 30 times longer than the metal bellows used in a conventional MH actuator. These findings support the efficacy of the soft MH actuator using the LaNi5 alloy with low plateau pressure and laminate film bellows for the purpose of developing a portable rehabilitation system or a wearable force feedback device in virtual reality.

采用LaNi5合金和层压薄膜波纹管的软金属氢化物致动器

康复系统和辅助技术设备为中风或衰老过程造成的运动障碍的人需要一个人性化的驱动器，柔软，紧凑，缓慢，无噪音，环保。为了实现这类执行器，我们设计了一种采用镀铜LaNi5合金和层压薄膜波纹管的软金属氢化物(MH)执行器。为此，我们选择了合适的LaNi5合金，并为软MH执行器开发了一种柔软轻便的末端执行器。实验结果表明，在室温下具有较低平台压力的LaNi5合金在MH作动器中表现良好。此外，应用于由铝层压薄膜制成的软波纹管的末端执行器比传统MH执行器中使用的金属波纹管轻20倍，长30倍。这些发现支持了使用低平台压力LaNi5合金和层压薄膜波纹管的软MH执行器的有效性，用于开发便携式康复系统或虚拟现实中的可穿戴力反馈设备。
