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.
