Paper Abstract

Recently we proposed a mechanical mover device in a unimorph structure with powder hydrogen storage alloy dispersed. A silicone rubber sheet with the alloy was piled up on another pure silicone rubber sheet, then mechanical movement was generated by hydrogen gas absorption and desorption. Because the response of the movement was slow, therefore, in this research we tested the additive effect of catalyst of Pd-Al2O3 powder into the hydrogen storage alloy powder before mixing with rubber. The mover device with the catalyst indicated drastically modified responses, such as higher initial moving rate and also larger displacement. The results suggested the possibility of the device for medical purpose such as catheter because of a powerful but tender characteristic of the device.
