“…224 Ionic polymer−metal composites (IPMCs) consist of a solvent swollen ion-exchange polymer membrane laminated between two thin flexible metals (typically percolated Pt nanoparticles or Au). 226,227 Application of a bias voltage to the device results in the migration of mobile ions within the film to the oppositely charged electrode causing one side of the membrane to swell and the other to contract, resulting in a bending motion. 228 Over time the actuator slightly relaxes due to the built-up pressure gradient.…”

Haptics involves human touch sensing and tactile feedback and plays a crucial role in physical interactions of humans with their environment. There is an ever‐increasing interest in development of haptic technologies, due to their role in various applications such as robotics, virtual and augmented reality, healthcare, and smart electronics. Electrically driven actuation mechanisms for soft materials like dielectric elastomer actuators (DEAs), electrohydraulic soft actuators (ESAs), ionic polymer−metal composites (IPMCs), and liquid crystal elastomers (LCEs) hold the potential for the development of the next generation of haptic feedback devices due to a variety of advantages such as light weight and compact design, untethered activation and control, large actuation strains, and distributed and localized actuation. Herein, a detailed look is taken at the advancement in material designs for these electrically driven soft actuators. A detailed analysis of the different strategies for improving the electromechanical performance of existing material systems is presented. Approaches adopted to synthesize novel material systems are explained. Advancements in compliant electrode materials for the electrically driven soft actuators are also described. The conclusion reflects on the main challenges in the field and provides perspectives on recent advancements expected to have a significant impact.
