ABSTRACT:
A biomimetic electrode material including a fibrous matrix including a conductive polymer and an ion conducting polymeric material is described. The biomimetic electrode material may be used in a number of body-implantable application including cardiac and neuro-stimulation applications. The biomimetic electrode material can be formed using electrospinning and other related processes. The biomimetic electrode may facilitate efficient charge transport from ionically conductive tissue to the electronically conductive electrode and may induce surrounding tissue to attach or interface directly to the implanted device, increasing the biocompatibility of the device.
