Electro-active polymer, one of smart materials, is a new alternative technology, which can get an ultra precision movements and bio-compatibilty. This paper presents the relationship between elastic modulus and maximum deflection as a key property of maxwell stress effects and also presents the relationship between dielectric constant and maximum deflection as a key property of electro-striction effects in disc-type actuators using segmented PU. To induce equation about distributed load of a disc, we use boundary condition of fully clamped circular plate and to obtain design parameters of a micro-fluidics system, CFD simulation is performed.
