 Polymer-based conductive electrodes have become increasingly important in the development of flexible, transparent, and sensing electronic devices due to their unique properties such as flexibility, transparency, and mechanical stability. In particular, Poly-3-4 ethylenedioxy-o-fine polystyrene sulfonate, PETIT, PSS, has emerged as one of the most promising flexible electrode materials due to its high electrical conductivity, mechanical compliance, and stability. This review provides an overview of recent advances in the field of PETIT, PSS, including its fabrication methods, applications, and limitations. It also discusses the potential of PETIT, PSS in future applications, such as wearable, deformable, printable, and ultra-thin electronics.
