Conductive polymers are one of the main categories of electroactive polymers that have been proved to be ideal materials for fabricating artificial muscles. Artificial muscles based on conducting polymers exhibit many superior characteristics

such as lightweight

low power driving

micro-machining

and biocompatibility. These characteristics make a significant contribution to their wide application in the fields of the biomedical devices. Although a large number of studies have been carried out on the construction of conductive polymer artificial muscle in the past

few reviews have been published. The driving mechanism and factors affecting the driving performance of conductive polymer artificial muscle

as well as their biomedical applications

are discussed in this review. Furthermore

some suggestions on the challenges it faces are proposed.
