Abstract
Provided is a method for creating fluid motion of an electro-sensitive movable fluid upon application of direct-current-voltage between two electrodes adjacent the fluid, the fluid having a conductivity &sgr;, and a viscosity &eegr; located inside a triangle in a graph showing a relation between a conductivity &sgr; plotted as abscissa, and a viscosity &eegr;, plotted as ordinate, of a fluid at the working temperature, said triangle having, as vertices, a point P indicated by the conductivity &sgr;=4×10 S/m and the viscosity &eegr;=1×10 Pa·s, a point Q indicated by the conductivity &sgr;=4×10 S/m and the viscosity &eegr;=1×10 Pa·s, and a point R indicated by the conductivity &sgr;=5×10 S/m and the viscosity &eegr;=1×10 Pa·s.
