Abstract
This paper presents a novel microgenerator of $CO_2$ (carbon dioxide) gas. $NaHCO_3$ (sodium bicarbonate) in a chamber is decomposed by the underlaid microheater. Alternatively, water droplet is caged by paraffin layer and released by heating. The released water dissolve HOC(COOH)$(CH_2COOH)_2$ (citric acid) powder and then, $NaHCO_3$ reacts with the solubilized HOC(COOH)$(CH_2COOH)_2$ and $CO_2$ is produced. Micropumps actuated by $CO_2$ generation were fabricated. A portable micro cell incubator of which pH is controlled by the produced $CO_2$ is also presented as one of the further applications.
