The idea of using electrosensitive fluid for fluid power control is not new. However, most of the available information is of an experimental nature. This paper presents an attempt to model the behaviour of an insulating fluid containing concentrations of small dielectric particles. Results of this analysis show that the pressure required to push the mixture between parallel plates is proportional to the square of the applied voltage. The model also indicates that the performance of the mixture is dependent on particle size and concentration of solids. Reasonable, good experimental evidence is included to support these conclusions.
