Abstract

The hydrogen emission characteristics of a hydrogen storage alloy operating system employing the Zr0.9Ti0.1Cr0.6Fe1.4 alloy were analyzed under different temperatures and loading conditions for application in a rehabilitation system for motion assistance for the aged and disabled. After activating 8.56g of a Zr0.9Ti0.1Cr0.6Fe1.4 alloy under a 5.5MPa hydrogen atmosphere, operation tests were conducted in the temperature range of 25–80^∘C under the loading conditions of 5–45kg. The lightest load of 5kg was lifted by 150mm when the system was heated from the initial test temperature of 25–80^∘C and a 40kg load was lifted by 12.5mm at 80^∘C, while a 45kg load could not be lifted under any of the temperature conditions. The hydrogen storage alloy operating system developed in this study is expected to be useful in motion assistance for the socially underprivileged, as a rehabilitation tool for the hand, wrist, and elbow, as supplementary equipment, and in rehabilitation systems for daily life.
