Micro/nanofluidic electrokinetic energy conversions

''The classical electrokinetic energy conversion mechanism relies on a single stage conversion by forcing liquid through a channel with charged walls. When the net charges inside the electrical double layer (EDL) are transported by water flow, the produced electrical energy can be harvested via connection of electrodes at two ends of a channel. Different from the classical electrokinetic energy conversions, we developed “ballistic energy conversion” by using high speed charged micro-droplets. With the acceleration-deceleration stage of water, it enables to convert kinetic energy of micro-droplets to electricity, with maximal efficiency to nearly 50% and recently to 80%, which proved our theoretical predictions. Self-excited energy conversion system was invented that only requires water, micropore and pressure to gain electricity.''
