用于因中风或衰老过程导致运动障碍的人的康复系统和辅助技术设备需要柔软、紧凑、缓慢、无噪音且环保的人性化致动器。为了实现这些类型的运动康复系统，我们设计了一个软金属氢化物（MH）驱动器使用层压波纹管。为了这项研究的目的，我们开发了软，轻波纹管制成的多层复合膜。作为实验测试的结果，这种叠层波纹管比传统MH致动器中使用的金属波纹管轻20倍，长30倍。使用叠层波纹管的软MH致动器具有氢不渗透性、弯曲耐久性和足够的人体关节被动顺应性。使用叠层波纹管的MH驱动器可以以足够慢的速度驱动，并且对于人体肢体的康复是足够安全的。这些初步的研究结果支持的功效的软MH致动器与层压波纹管的目的，开发一个运动康复系统或可穿戴力反馈装置在机器人治疗。
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 kinetic rehabilitation systems, we design a soft metal hydride (MH) actuator using a laminate bellows. For the purpose of this study, we develop the soft and light bellows made of a multilayer laminate film. As a result of experimental tests, this laminate bellows is 20 times lighter and 30 times longer than a metal bellows used in a conventional MH actuator. The soft MH actuator using the laminate bellows has hydrogen impermeability, flex durability and adequate passive compliance for human joints. The MH actuator using the laminate bellows can drive at a slow and safe enough speed for rehabilitation of human limbs. These preliminary findings support the efficacy of the soft MH actuator with the laminate bellows for the purpose of developing a kinetic rehabilitation system or a wearable force feedback device in robotic therapy.
