Abstract：In order to solve the problems of shortage in new technology area， such as actuator， artificial muscle，biorobot etc., the electroactive polymeric materials electricacrylic elastomer was investigated.The analysis of the driver characteristics of dielectric elastomer was done.Through experiments,  the main factors of affecting EACE material active zone （electrode coating regional） area strain were  researched. The relationships between active zone area strain and these influencing factors were found out . Thereby appropriate conditions which can get required active zone area strain were determined according to relationships between them. The results show that：whether uniaxial prestretching or the uniform and nonuniform biaxial prestretching, the general trend of the effects of the active zone area strain are increased first and then decreased with the amount of stretching increases. The active zone area strain is increased with increasing applied voltage， reduced with the active zone and the window radius ratio increasing. By analyzing the experimental results, it shows that search for suitable conditions on the active zone to generate the required area strain is very important.
