Abstract
This paper reports a previously overlooked mechanism that has a considerable effect to undermine bubble-driven micropumping in a square-shaped microchannel, and therefore limits the maximum achievable pressure head. Improvement of pumping performance by rounding the microchannel is thus proposed.
