“…In addition, the low working voltage (2–3 V) also complies with the working range of the proposed system, being easy to integrate with other equipment and possibly preventing biological damage in applications. [ 36 ] When a specific voltage is applied to both sides, the prepared actuator strip exhibits a large bending deformation, and the degree of bending can be determined by varying the applied voltage bias (Figure 5e; Figure S10, Supporting Information). Owing to the capacitor structure, the I–V curve of the actuator presents the electrochemical characteristics of a double‐layer supercapacitor (Figure S11, Supporting Information).…”

The simulation of human feelings, perceptions, and actions has become an important application field for medical treatment, human-computer interfaces, and intelligent robots. However, the need for various functional units hinders system integration. A threshold-switching memristor is used as the sympathetic nerve center to simulate an unconditioned reflex. High current nonlinearity (10 6 ) is achieved by adopting a nanocontact structure, and high flexibility (bending radius of ≈5 mm) is obtained by combining the structure with a flexible polymer film. Furthermore, integrating a flexible sensor and a flexible artificial muscle made of ionic polymer-metal composite allows to form an all-flexible complete reflex arc of an unconditioned reflex. The threshold-switching memristor can provide strain-dependent control through simple control logic, indicating the great potential of adopting thresholdswitching memristors for primary neuromorphological control and flexible intelligent medical treatment.

“…For fabrication of IPMC actuator Nafion-117 is used as base polymer (thickness of 0.183 mm). The Ag-IPMC fabrication followed the traditional scheme composed of surface roughening, adsorption, reduction and developing process, which was proposed in [23]. The dimension of the fabricated IPMC was 45 mm × 25 mm × 0.…”

This work presents development of an effective non-linear mathematical model for dynamic analysis of Ionic polymer-metal composites (IPMCs) cantilever actuators undergoing large bending deformations under AC excitation voltages. As the IPMC actuator experiences dehydration (solvent loss) in open environment, a model has been proposed to calculate the solvent loss due to applied electric potential following Cobb-Douglas production method. D’Alembert’s principle has been used for the derivation of the governing equation of motion of the system. Generalized Galerkin’s method has been followed to reduce the governing equation to the second-order temporal differential equation of motion. Method of multiple scales has been used to solve the non-linear equation of motion of the system and dehydration effect on the vibration response has been demonstrated numerically.

“…Electroless plating method was adopted for the preparation of Ag-IPMC actuator. A conventional Ag-IPMC as a reference sample was also fabricated by following the methods that was proposed by Biswal et al [14]. The new method for fabricating multilayered Ag-IPMC was performed without repeating the initial compositing process, called reduction/primary plating process over conventional Ag-IPMC.…”

Ionic polymer-metal composites (IPMCs) are electro-active polymers that undergo bending deformation with the stimulus of a relatively small electric field. In this research we fabricate multilayered structure of IPMC actuator using chemical decomposition method and investigate the influence of bending response on applied input voltage. The experimentally obtained results had been compared to single layered IPMC actuator. The result shows that the increment of layer on base material (Nafion-117) had increased the actuation capability of IPMC actuator. The tip displacement increases up to 20% for three layered and around 30% for four layered compared to single layered IPMC actuator under the application of 1.0V. This finding would be useful for the application where higher bending displacement is required i.e., in the robotic and biomimetic application with a very small input voltage.
