This paper presents the results of theoretical study designed to measure the suitability of a dielectric elastomer as an actuator, from a group of acrylic and silicone elastomers. The micro molecular parameters of elastomers such as monomer type, monomer chain length and density were taken into consideration for analysis of actuation properties. Identification of monomer type of selected elastomers was done by using modified dielectric equations of polarization and stress induced due to applied electric field. The effect and the importance of electric field on the selected elastomers were also considered. To further understand the actuation potential of polymers, a comparison was done on the basis of their stress-electric field analysis. A conclusion was drawn on the basis of these comparisons and recommendations are given for an effective selection of polymers for use in actuator applications.
