Abstract
A microfluidic pump comprises a plurality of metal electrodes () which oxidise in air, a liquid droplet () to be moved by the pump, which is in contact with a least one metal electrode, and a controller for controlling the oxidation state of the metal electrodes in order to vary the electrode wettability. This arrangement enables full integration with a semiconductor device, and with low drive voltages.
