“…The materials of the electromechanical actuators can be divided into three main types: metal‐based, nanocarbon‐based, and polymer‐based, which are actuated based on different principles including changes in the lattice parameters, changes in valence states, chemical adsorption of ions, intercalation and delamination of ions, inhalation and detachment of ions, and inhalation and detachment of H 2 O molecules. [ 144 ] When a voltage is applied on the electrode layers, these actuation mechanisms all lead to bending deformation. The electromechanical actuators show some significant advantages in low actuation voltage, high strain, and fast response, which are suitable for low‐voltage actuator development and wearable actuation system integration.…”

Soft actuators have been an important research focus in robotics due to their advantages in nondestructive contact and excellent motion adaptability, which enable flexible manipulation, extreme environments exploration, and in vivo surgical treatment. Various soft robots actuated electrically, magnetically, optically, and fluidically are built toward different application scenarios. Among them, electrical actuation method is an advanced choice to actuate and control soft actuators that are expected to be compatible and integrated with existing industrial robotic systems and wearable intelligent devices. Current robotic systems have higher requirements on the actuators’ function, which can be explored through material and structural designs. Based on a variety of deformable materials, the structural design enables the soft actuators to span from low dimension to high dimension with further improvement in function. Therefore, in this review, 2D and 3D electrical‐based soft actuators from the perspective of dimension design are introduced, which involve functional materials, structure design, and fabrication technology. Some novel 3D fabrication methods, such as the 3D compressive buckling process, are summarized to build 3D soft robots. This review aims at offering important guidelines for the development of soft actuators and the construction of integrated robotic systems in the future.

“…Unlike electronic EAPs, ionic EAPs are usually related to electrochemical actuation because of their ability to exchange ions with the surrounding electrolyte . Electrochemical actuation, known for its low voltage requirements and large actuation amplitude, is categorized into pseudocapacitance and electric dual-layer capacitance, depending on the occurrence of redox reactions. − By controlling the adsorption/desorption of ions, the electric dual-layer capacitance achieves actuation, and carbon-based materials are the most common electrode material.…”

Fiber/textile-based actuators have garnered considerable attention due to their distinctive attributes, encompassing higher degrees of freedom, intriguing deformations, and enhanced adaptability to complex structures. Recent studies highlight the development of advanced fibers and textiles, expanding the application scope of fiber/textile-based actuators across diverse emerging fields. Unlike sheet-like soft actuators, fibers/textiles with intricate structures exhibit versatile movements, such as contraction, coiling, bending, and folding, achieved through adjustable strain and stroke. In this review article, we provide a timely and comprehensive overview of fiber/textile actuators, including structures, fabrication methods, actuation principles, and applications. After discussing the hierarchical structure and deformation of the fiber/textile actuator, we discuss various spinning strategies, detailing the merits and drawbacks of each. Next, we present the actuation principles of fiber/fabric actuators, along with common external stimuli. In addition, we provide a summary of the emerging applications of fiber/textile actuators. Concluding with an assessment of existing challenges and future opportunities, this review aims to provide a valuable perspective on the enticing realm of fiber/textile-based actuators.
