碩士 === 國立清華大學 === 工程與系統科學系 === 95 === This study conducts experimental investigation associated with energy transfer by using a device with a microchannel.. Our experimental results verify that the design and material of channel strongly influence the power .efficiency; the best voltage and current obtained is 0.9V and 8X10-9A in our experiments. With the decrease of the electrolyte concentration, the streaming potential increases. The streaming potential held at a saturated value or dramatically decay when the electrolyte concentration is below a certain critical value(10-7M).The streaming potential of the device with the oxidized PDMS slightly decay, as the ZETA potential of the oxidized PDMS surface is not constant.
