Abstract
This paper proposes an active air mattress that improves utility of an cxoskeleton. The utility of the wearable assistive device is comprehensively judged by several items such as easiness to wear, body holding, pressure distribution and blood flow in holding area, humidity of forearm skin, and so on. This paper focuses on easiness to attach the exoskeleton on a user finger and stability of finger holding. Through some experiments, we confirm that the active air mattress improves easiness to wear by comparing with a conventional fasten device, a magic tape, and that stability of finger holding is as same level as the conventional one.
