Abstract: Electro-responsive materials are a kind of smart material with the ability to alter their mechanical or physical properties in response to an external electric field. Due to their unique properties, electro-responsive materials can be implemented in smart structures, such as soft actuators, deformable wings, artificial muscles, flexible cells, smart fluids dampers, stiffness tunable isolators, sensing concretes, and so on. The preparation, testing, mechanisms, theories, and applications of electro-responsive materials are of interest to scholars in smart materials and structures. In the preparation of these materials, one key task is to find optimal compositions to achieve stability yet maximize their physical response to the external electric field. Another priority is to develop electro-responsive materials with various physical responses. In properties testing, the key task is to develop methodology to measure the response more accurately. In engineering applications, the focus is on exploring the application of electro-responsive materials in such fields as materials, mechanical engineering, civil engineering, biomedical devices, space exploration, and stretchable electronics.
