Abstract
This work presents bio-inspired microfluidic channels that form liquid diodes and that are then equipped with a needle-like electrode to create 'liquid triodes' analogous to electronic triodes. The devices transport liquid uni- or (bi)directionally over centimeters at velocities in the range of mm/s in response to high-voltage signals. Fabrication involves laser ablation. The topography of the microfluidic channels was analyzed by optical coherence tomography (OCT). The components have potential applications in bio-medical microfluidics, labs-on-a-chip, lubrication, filtration, and electronics cooling.
