Conforming to the design criteria of matching the human gait and muscle impedances, our research group has recently come up with the concept and design of exploiting the streaming potential induced by electrokinetic squeezing liquid flows as a potential candidate of wearable micro power generation. The goal of this research project is therefore aimed at systematically investigating the underlying physical mechanisms governing the mechanical to electrical energy conversion processes via electrokinetic squeezing liquid flow streaming power generation, and at examining the feasibility of applying the electrokinetic squeezing flow technology in the development of micro power generating devices housed or hosted within the sole or midsole of the shoe. Through experimental measurements and theoretical analyses, we shall investigate and discuss how variations in the non-Newtonian rheology, non-linear boundary slip, electrical double layer overlap, and the non-parallel geometry of the squeezing plates may affect or influence the open circuit voltage, short circuit current, current-voltage relationship, matching of the internal and external impedances, energy conversion efficiency, and energy density during electrokinetic squeezing liquid flow energy conversion. Moreover, we shall also consider the power generation mode of multiple squeezing flow channels arranged in parallel with an external load resistance so that both the amount of electrical current output and overall energy density can be substantially increased. With the ultimate goal of developing an effective electrokinetic squeezing flow power generation device, we further explore and discuss the optimal design or spatial arrangement of the flow channels, electrodes, and liquid reservoirs as well as the optimal temporal synchronization or optimal time sequence for squeezing motion among the multiple squeezing flow channels. Hopefully, the theory and technology developed throughout the course of this research can not only make innovative contributions to the fields of electrokinetics, microfluidics, non-Newtonian rheology, and energy harvesting, but also be found as competitive among the existing piezoelectric, triboelectric, dielectric elastomer, or electromagnetic induction wearable micro power generating technologies.電動力效應能源採集非牛頓流體力學壓擠流流動位勢穿戴式元件electrokinetic effectsenergy harvestingnon-Newtonian fluid mechanicssqueezing flowstreaming potentialwearable devices
