Abstract:

A new high power bi-material actuator, driven by the large volume expansion of hydrogen storage LaNi5 alloy film on a polyimide substrate, was prepared using a flash evaporation method. The reversible shape change was operated by hydrogen absorption and desorption. In order to apply this material to a practical actuator, the load dependence of strain yielded by shape change is an excellent potential. In this study, the strain was measured under different loading stresses. The results showed that large shape changes were induced by hydrogen operation under large loading stress.
