Design and simulation of non-uniform electric field using mesh electrodes for electrorheological micro valves

The refresh rate of two-dimensional tactile information for visual impaired people using electrorheological (ER) technology is directly related to the flow an ER valve. bigger is, faster refreshed. For a parallel electrodes valve configuration, due limitation Braille standard width valve, gap channel which also only adjustable parameter benefit and at same time enhance operating voltages contribute big part costs display system. A new mesh configuration introduced decouple from while cross section determined by parameters electrodes. quantity effective electric field strength interaction space unit used evaluate anisotropy governed influences geometrical applied on were analyzed COMSOL Multiphysics. simulation results show that increases with wire diameters, decreases clearances. These provide fundamental laws designing micro non-uniform some applications.
