Flexible Conductive Paper-Based Sensors for On-Skin Electrophysiological Monitoring and Wearable Applications.

ABSTRACT: Flexible, skin-conformable electrodes require materials that combine mechanical robustness, environmental stability, high electrical performance, and biocompatibility. Here, we present a flexible conductive composite film composed of poly(3,4-ethylenedioxythiophene):polystyrenesulfonate (PEDOT:PSS), cellulose nanofibers (CNF), and the ionic liquid 1-ethyl-3-methylimidazolium ethyl sulfate (EMIM ES). The composite is fabricated via a simple aqueous blending and filtration process, yielding a free-standing film with a robust fibrous microstructure. ATR-FTIR analysis confirms the successful integration of all components, while SEM imaging reveals a percolated nanofibrillar architecture that enhances interfacial adhesion and structural integrity. Mechanical testing reveals a tensile strength o
