Paper Abstract

In this study, the effects of surface treatments were investigated on the mechanical response of the LaNi5 thin film actuator deposited on polyimide substrates. Since controlling the hydrogen concentration in film by reversible pressure change drives this actuator, this film actuator can be expected as a sensor and/or a controller of hydrogen gas flux in various hydrogen-related devices. This significantly improved mechanical response was attributed to the switching of the reactions in the rate determining steps.
