A Matrix of Valves Based on Electro-Rheological Fluid and its Application on Multi-Line Braille Displayer

Article Preview

Abstract:

A valve based on electro-rheological fluid (ERF) is introduced for its possibility of being a very small volume and power consuming. A novel linking method of these multiple valves and their control strategy contribute to the accomplishment of saving the numbers of power modules and the system power consuming, eventually the volume and weight of the system. For a N times M valves matrix, the saving numbers of power modules used for driving these valves are the difference between the product of N and M, and the plus of N and M. It provides a novel solution of shrinking system for a portable mechatronic embedded system application. A demonstration of these valves matrix on multi-line Braille displayer for blind people is shown.
