 Ionic polymer metal composites, IPMCs, are a type of artificial muscle material that can be used in biomedical devices, flexible robots, and microelectromechanical systems, men's. These materials consist of a proton exchange membrane sandwiched between two electrodes, which allows ions to move from one side to the other when electricity is applied. This movement causes the material to expand or contract, depending on the direction of the current flow. Recent advancements in the fabrication and characterization of conductive materials, such as carbon-based materials and conductive polymers, have led to improved performance of these materials. Additionally, modifications to the proton exchange membrane and electrodes have been made to improve their functionality. These improvements have allowed for the development of new applications for IPMCs, including robotics, MEMS, and biomedicine. This article was authored by Hao Zhang, Xiao Huolin, Yonghu, and others.
