Very high dielectric strength for dielectric elastomer actuators in liquid dielectric immersion

Very high dielectric strength for dielectric elastomer actuators in liquid dielectric immersion

This letter reported that a dielectric elastomer actuator (3M VHB), which is immersed in a liquid dielectric bath, is enhanced tremendously in dielectric strength up to 800 MV/m, as compared to 450 MV/m for the actuator operated in air. The bath consists of silicone oil (Dow Corning Fluid 200 50cSt)...
