Dielectric elastomers are a kind of new textile materials that can be deformed under energy-excited electric field to perform energy conversion. They belong to electroactive polymers

and electroactive polymers have electronic and ionic types. Dielectric elastomers have broad application prospects in the design of flexible actuators. However

there are still many technical difficulties. There is still a need for more in-depth studies on the composition of elastomeric matrix materials

optimization of flexible electrode materials

and energy harvesting. In this paper

after clarifying the working principle and classification of the dielectric elastomer

it summarized the electrode

pre-stretching

temperature and energy collection

etc.

and prospected its application prospects.
