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
