Electroactive dielectric polymer gel (DPG) as a class of electronic type electroactive polymers has important applications in soft robot, wearable electronics, and biomedical fields due to their lower driving voltage, degree of various

actuation freedoms, and high actuation strain. The DPG materials are often

composed of solid and liquid phases which are made by polymer network and

high dielectric constant of solvent (or plasticizer). Accordingly, the electromechanical coupling mechanisms of DPGs are more complex and are different with

other electronic electroactive polymers. In addition, the DPGs have many

advantages for soft actuators such as lower driving voltage, larger actuation

strain, and various actuation freedoms. As far as we know, the concept and

progress of DPGs have not been systematically reported so far. In this review,

we completely reviewed recent progresses of electroactive DPG materials,

electromechanical coupling mechanisms, and applications of DPG actuators, etc.

This review can provide more understanding, current challenges, and future

trends of electroactive DPGs and their applications in soft actuators
