Patent number: 9132425Abstract: Electronic-fluidic hybrid form dividers, constructed by a simple planer droplet generation structure, a pair of signal electrodes, and a responsive control valve, which is programmed to respond to only certain signal droplets, by a basic electronic principle: change of voltage share between impedances. Detected fluidic information is addressed in both electronic and fluidic forms, and the fluidic pathway is well-confined in a simple planar structure, although its control valve is in a second layer, thereby minimizing any fluidic disturbance. Various configurations comprise a plurality of identical structures, which can alter their cumulative function by re-assignment of required voltage share. The hybrid divider can be assembled into a fluidic universal logic gate, of a simple two inlet and one outlet signal channels structure, and switch between sixteen functions by re-assigning voltage share.Type: GrantFiled: April 11, 2011Date of Patent: September 15, 2015Assignee: THE HONG KONG UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Weijia Wen, Limu Wang, Xiang Wang, Shunbo Li
