A non-Newtonian fluid (140) is used in an electrokinetic device to produce electroosmotic flow therethrough. The nonlinear viscosity of the non-Newtonian fluid (140) allows the electrokinetic device to behave differently under different operating conditions, such as externally applied pressures and electric potentials. Electrokinetic devices can be used with non-Newtonian fluid (140) in a number of applications, including but not limited to electrokinetic pumps, flow controllers, diaphragm valves, and displacement systems.

La présente invention concerne l'utilisation d'un fluide non newtonien dans un dispositif électrocinétique pour y produire un flux électroosmotique le traversant. La viscosité non linéaire du fluide non newtonien permet de faire varier le comportement du dispositif électrocinétique en faisant varier les conditions de fonctionnement, et notamment les pressions appliquées extérieurement et les potentiels électriques. Ces dispositifs électrocinétiques sont utilisables avec un fluide non newtonien dans plusieurs applications, et notamment les pompes électrocinétiques, les régulateurs de flux, les robinets à membrane, et les systèmes de déplacement.
