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. |
