Load Dependent Bending Motion Driven by LaNi5 Hydrogen Storage Alloy Film Deposited on Copper Thin Sheet

Abstract

To obtain the high power mover device with high responsiveness, mover devices driven by hydrogen storage alloy film have been successfully developed. The effect of load on bending movement of LaNi 5 hydrogen storage alloy film deposited on thin copper substrate has been studied. The thin copper sheets, 10 mm in thickness, have been prepared by cold rolling. As a result, the power of the mover device is higher than that of the Ni Ti shape memory alloy commercially used.
