Abstract
This letter proposes a novel hybrid pneumatic power source for the development of a portable pneumatic source. The hybrid pneumatic source achieves a lightweight system by combining two pneumatic sources: one that can generate high pressure/small suppliable flow and one that can generate small pressure/large suppliable flow. In this study, first, the mobility of various pneumatic sources is evaluated by experiments. The evaluation methods involve a small battery-driven compressor, tank, phase change of material, and chemical reaction. From the results, it is clarified that there is no best method because each method has advantages and disadvantages. Then, a hybrid pneumatic source utilizing the result is proposed. Finally, a prototype that has phase change of CO2 and dimethyl ether as a pneumatic source is developed, and the effectiveness of the proposed method is confirmed by experiments.
