Recent progress of dielectric polymer composites for bionics

Abstract

Natural structures, natural phenomena, animal and plant forms, and human behavior always provide us with inspiration and stimulate more creativity. The design and application of dielectric polymer composites that can be utilized to fabricate artificial muscles show great potential in the field of bionics. However, great challenges still exist, which severely prevent the development of dielectric polymer composites. In this review, we systematically surveyed recent advancements in nature-inspired monolayer and multilayer dielectric polymer composites with excellent properties, as well as the description of their structures and characteristics. In addition, we further discussed the applications of such composites in integrated systems for the development of bionic robotics, healthcare and biomedical applications. Moreover, an in-depth analysis of challenges and prospects in this field was also provided. Mimicking nature has become essential for the design and application of dielectric polymer composites, and we believe this approach will drive continued advances in the intelligent and medical industries.
