Electrowetting on dielectric (EWOD) is useful in manipulating droplets for digital (droplet-based) microflui-dics, but its high driving voltage over several tens of volts has been a barrier to overcome. This article presents the characteristics of EWOD device with aluminum oxide (Al 2 O 3 , e r & 10) deposited by atomic layer deposition (ALD), for the first(More)
Shadow image based high-throughput continuous cell monitoring technique is proposed. Shadow image variations of human alveolar epithelial cells (A549) cultured in a custom built incubator are analyzed qualitatively and quantitatively. Two measures which correspond to the morphology change of the cells are suggested and defined. Within this platform, it is(More)
In this paper, a novel electrostatic two-step micromirror which can serve as a pinhole and be driven at low voltages is presented. We have designed, fabricated and tested the two-step micromirror. It has a novel structure with an intermediate moving plate. The fabricated device has successfully demonstrated the reduction of the driving voltage. The proposed(More)
