金属氧化物可以通过分别加热或冷却氧化物而在可逆反应中吸收和解吸氢。我们开发了一种执行器，包括覆盖有铜壳的金属波纹管（直径23 mm，高6 mm），用于加热或冷却波纹管的Peltier元件（38 mm x 38 mm x 5 mm），以及带金属波纹管的气缸（直径46 mm，高73 mm）。从实验结果中，它被发现，吸氢的速度比解吸快，但是，它的速度增加的重量的气缸上的负载的增加。在22.5kg载荷下，该驱动器可在50s内产生25mm的单行程位移。此外，开发了一种由液压缸、帕尔贴元件和金属氢化物组成的双作用型金属氢化物执行器，并将其应用于残疾人升降机。
Metal hydrides can absorb and desorb hydrogen in a reversible reaction by heating or cooling the hydrides, respectively. We have developed an actuator consisting of metal hydrides covered with a copper case (diameter 23 mm, height 6 mm), Peltier elements (38 mm x 38 mm x 5 mm) to heat or cool the hydrides, and a cylinder (diameter 46 mm, height 73 mm) with metal bellows. From the experimental results, it was found that the velocity of hydrogen absorption was faster than the desorption; however, its velocity increased as the weight of the load on the cylinder increased. The actuator could produce a one stroke displacement of 25 mm within 50 s in the case of a 22.5 kg load weight. Furthermore, a double acting type metal hydride actuator composed of a hydraulic cylinder, Peltier elements, and metal hydrides was developed and applied to a lifter for the disabled.
