TLDR
In this paper, the authors present a theory of dielectric elastomers, developed within continuum mechanics and thermodynamics, and motivated by molecular pictures and empirical observations, which couples large deformation and electric potential, and describes nonlinear and nonequilibrium behavior, such as electromechanical instability and viscoelasticity.About:

TL;DR: A class of soft actuators is described, termed hydraulically amplified self-healing electrostatic (HASEL) actuators, which harness a mechanism that couples electrostatic and hydraulic forces to achieve a variety of actuation modes and demonstrate their robust, muscle-like performance as well as their ability to repeatedly self- heal after dielectric breakdown.

Multi-functional dielectric elastomer artificial muscles for soft and smart machines
TL;DR: The octopus arm is an example of a soft actuator with a virtually infinite number of degrees of freedom (DOF) as discussed by the authors, which utilizes neural ganglia to process sensory data at the local “arm” level and perform complex tasks.

Functional hydrogel structures for autonomous flow control inside microfluidic channels
David J. Beebe,Jeffrey S. Moore,Joseph M. Bauer,Qing Yu,Robin H. Liu,Chelladurai Devadoss,Byung Ho Jo +6 more
TL;DR: The fabrication of active hydrogel components inside microchannels via direct photopatterning of a liquid phase greatly simplifies system construction and assembly as the functional components are fabricated in situ, and the stimuli-responsive hydrogels components perform both sensing and actuation functions.
