Description
Jeongmok Kim and co-authors built a tiny pump powered by baker yeast, in work published in 2026. As yeast ferments sugar, it makes gas that builds pressure in a sealed space. The team used that pressure to push fluid through small channels, with no outside power.
They measured how gas built up over time and fit the trend with simple equations. A full model used four inputs, and a shorter form used just yeast mass and sugar strength. Both matched the test data well within the range tried. The authors see uses in space tests, school tools, and places with little power, where a cheap living pump could run on its own.
