    摘要: A technique has been developed to fabricate micro- or nanopumps based on porous alumina thin films. The main body of the nanopump consists of a porous alumina thin film (containing nano-sized channels of about 40-300 nm in diameter) with conductive surfaces (e.g. Au coating layers) on both sides of the film. Through the fabrication of nanochannels in (the alumina films) and the subsequent annealing and surface activation processes, high-efficiency micro- or nanopumps can be made. The nanofluidic flow through the nanochannels of the alumina thin films is driven by an electric field with no moving parts. The flow rate (up to 50 millilitres/(min·cm2)) of water through the alumina thin film can be continuously tuned through the intensity of the electric field, i.e., the DC electric potential applied across the nanochannels.

    摘要: A rapid response relative humidity sensor based on nano-structured aluminum oxide thin film is disclosed. The main body of the sensor is an anodic aluminum oxide thin film of about 2-20 μm thick formed from an Al substrate which serves as one electrode. A porous metal layer of about 20-200 nm thick is formed over the anodic aluminum oxide thin film and functions as a second electrode. The alumina thin film contains nano-sized channels of about 10-100 nm in diameter, serving as a capacitive relative humidity sensor having high sensitivity and short response time. Thermal annealing at elevated temperature improves the linearity of the capacitance versus humidity curve, giving a full range humidity sensing range. Hysteresis and degradation are negligible for the humidity sensors.
