Development of Polymer Micro-actuator using Segmented Polyurethanes and its Application for the Micro-fluidics

세그먼트화 폴리우레탄을 이용한 고분자 마이크로 액츄에이터의 개발 및 마이크로 플루이딕스에의 적용

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.
