The high-dielectric material(BaTiO3)was added into polyurethane-acrylate(CN9021NS)to improve the dielectric properties of the composites.The effect of BaTiO3 dosage on the dielectric properties of polyurethane-acrylate was studied.The results showed that the addition of BaTiO3 could effectively increase the dielectric constant of the composites and reduce the energy loss of the actuator.This result effectively improved the electromechanical performance of various soft ro-bots.
