The paper presents a novel dielectric elastomer (DEA) fiber actuator that can be produced by the meter, offering a simple and scalable fabrication process. The fibers, made from silicone elastomer, are produced using a wet spinning method and then equipped with an ionic liquid as the inner electrode and an ionogel as the outer electrode. This design allows for actuation strains of up to 10% in both dry and wet environments, making it suitable for applications such as body-compliant actuators and wearables. The fibers exhibit excellent mechanical properties, including high extensibility and stability over 1000 cycles of deformation. The actuator's performance is further enhanced by bundling multiple fibers, mimicking human skeletal muscle bundles, and by using the fiber's length in folded configurations. The study demonstrates the potential of this fiber actuator for advanced soft actuator technologies, offering a versatile and scalable solution for various applications.The paper presents a novel dielectric elastomer (DEA) fiber actuator that can be produced by the meter, offering a simple and scalable fabrication process.
