“…The equivalent beam model equated the IPMC actuator to a cantilever beam and incorporated the material characteristics of the actuator into the model. Such models can predict actuator displacement, [10,17,[73][74][75][76][77][78][79][80] develop controllers, [81][82][83][84] optimize actuator performance, [73][74][75]77] and develop IPMC-based devices.

“…IPMC actuator exhibits significant nonlinear bending deformation through the complex coupling of mechanical, electrical, and chemical properties (Figure 6c). [ 77 ] A study utilized digital image correlation to derive the key relationship between the strain gradient and the excitation voltage, [ 77 ] as opposed to relying on assumptions and the elliptic integral method to develop an analysis model. Notably, the absolute node‐coordinate formula (ANCF) has been shown to be advantageous in studying the dynamics of flexible multibody systems with high geometric nonlinearities due to the strong coupling between large global motion and large deformation of structures and the physical nonlinearities associated with soft materials.…”

Compared to conventional actuators, the soft ionic polymer–metal composite (IPMC) actuator has significant advantages in specific applications, and the mathematical model of IPMC actuators is essential to comprehending and applying IPMCs. Due to the inherent characteristics of IPMCs and the impact of the manufacturing and measurement processes, it is challenging to developa reliable model. This article provides a comprehensive overview of the developments in IPMC actuator modeling. In particular, three types of models are examined and contrasted: the nonphysical identification model, the partial‐physical model, and the physical‐based model. In order to comprehend the current state of numerous IPMC actuator models, the characteristics, evolution, and functions of each type of model are discussed. Afterward, the evolution of the IPMC actuators’ applications is discussed. Finally, promising research directions for IPMC actuator models are identified that can more effectively facilitate the development of IPMC‐based devices.
