Abstract

This research navigates wearable electronic textiles (e-textiles),focusing on humidity sensors woven into fabric, aiming to enhancefunctionality in various applications like health monitoring. Theliterature review highlights the evolution of wearable humiditysensors, exploring different types integrated into textiles, fromcotton-based to carbon nanotube-infused materials. The study's coreinvolved developing conductive hemp fabric for potential use as ahumidity sensor. The experimental process treated hemp fabric withreduced graphene oxide (rGO) and polypyrrole (PPy) coatings. Theresulting rGO/PPy-coated hemp fabric displayed high conductivity,evidenced by low surface resistivity and powering an LED. This fabric'sresponsiveness to humidity variations indicated potential as ahumidity sensor, showcasing changes in electrical resistance withvarying humidity levels. The study concludes that the rGO/PPy-coatedhemp fabric exhibits promise as a wearable humidity sensor, withobserved sensitivity to humidity changes, likely due to watermolecule absorption altering its conductive network.
