摘要：

A novel 3D discrete T-shaped electrode array, fabricated by PolymMUMPs, is presented for pumping microscale liquid utilizing AC electro-osmosis (ACEO). Both the theoretical and experimental work has been carried out to evaluate the new design concept. A 3D finite element model of a unit cell incorporating a pair of electrodes is created to simulate pump performance. The new design is prototyped using the PolyMUMPs process and the experimental evaluation of its performance is conducted with saline solution at three different voltages. The maximum velocity obtained from the tracing particles at 30 mu m above the bottom of the channel was 90 mu m/s, 130 mu m/s and 200 mu m/s for a voltage of 6Vpp, 8Vpp and 10Vpp respectively.
