Paragraph starter
The practical application of dielectric elastomer actuators (DEAs) in soft robotics is significantly advanced by robust modeling techniques. As highlighted by Zhao and Meng (2026), DEAs present inherent challenges such as nonlinear elasticity and viscoelastic creep, which necessitate sophisticated physics-based or phenomenological models to accurately predict their electromechanical response. Effective modeling is a foundational step towards developing precise control and self-sensing capabilities, ultimately enabling more reliable and functional soft robotic systems.
