“…Zhang et al (2021) systematically analyzes the structural characteristics of IPMC and evaluates the effects of varying sample lengths (ranging from 1 to 5 cm with a width of 0.5 cm) on electrical parameters and actuation behavior. The study concludes that the electrical parameters of IPMC materials, such as capacitance, electrode resistance in the thickness-direction, and internal resistance, decrease as the sample length increases, while the bending strain of the setpoint increases [20].…”

This study focuses on mechatronic systems and their use of bending smart materials, specifically the ionic polymer metal composite (IPMC), for compliant actuation. The advantages of IPMC actuators, such as low power consumption and high flexibility, are highlighted. The actuation mechanism of IPMCs involving ion migration, water transport, and mechanical stress imbalance is discussed. The influence of geometric parameters, specifically length and width, on IPMC performance is investigated through simulations. Results show a positive correlation between IPMC lengths exceeding 30 mm and displacement, with longer lengths leading to higher displacements. The relationship between width and maximum displacement is attributed to factors like increased active area, larger polymer volume, and potential effects on mechanical properties. Further electromechanical analysis is needed for a comprehensive understanding of these mechanisms.
