Proposal of a fixation method for wearable assistive systems using jamming transition and the expansion of an elastic bag

A body fixing method for wearable assistive devices was proposed that utilized jamming transition and the expansion of an elastic bag. The proposed fixing part comprised a jamming layer, a rubber bag, and other components. The jamming layer deformed due to the application of pressure to an elastic bag. Then, it hardened due to negative pressure. In this research, we described the configuration and movement of the proposed method and conducted a sensory evaluation using a prototype.
