摘要 Ionic polymer-metal composite(IPMC)is an electro-active polymer material,which has many advantages such as small size,light weight,low driving voltage,large strain,and good biocompatibility.However,the conventional sheet IPMC has the shortcoming of only bending in the two-dimensional plane,which greatly limits the application of IPMC in the field of interventional surgery.In this work,a square rodshaped IPMC with multi-degree-of-freedom motion was fabricated,and the displacement and blocking force of the square rod-shaped IPMC in different directions are measured and analyzed under the DC voltage signal.An interventional catheter was designed using the square rod-shaped IPMC in order to achieve active guidance,and a simulation experiment platform and a model of human aorta were built to successfully complete the in vitro simulation experiment of interventional surgery,which preliminarily verified the feasibility of the square rod-shaped IPMC in the field of interventional surgery.
