Towards shape-adaptive attachment design for wearable devices using granular jamming.

ABSTRACT: Attaching a wearable device to the user's body for comfort and function while accommodating the differences and changes in body shapes often represents a challenge. In this paper, we propose an approach that addresses this problem through granular jamming, where a granule-filled membrane stiffens by rapidly decreasing the internal air pressure (e.g., vacuum), causing the granule material to be jammed together due to friction. This structure was used to conform to complex shapes of the human body when it is in the soft state while switching to the rigid state for proper robot functions by jamming the granules via vacuum. We performed an experiment to systematically investigate the effect of multiple design parameters on the ability of such jamming-based interfaces to hold against a lateral
