In recent years, flexible and soft strain sensors that convert mechanical deformation into electrical or optical signals have attracted great attention for use in wearable electronics and smart systems. These sensors show strong potential in areas such as human motion tracking, electronic skin, medical diagnostics, energy devices, and soft robotics. Partially reduced graphene oxide (PRGO) is a promising material due to its electrical conductivity, water dispersibility, and flexibility. Silver nanowires (AgNWs) also offer high conductivity, attributed to their high aspect ratio and interconnection. In this study, a nanocomposite hydrogel was developed by embedding PRGO and AgNWs into a hydrogel matrix for human motion sensing. Its key physical and functional characteristics, such as water content, gel fraction, strength, adhesion properties, and electrochemical behavior were tested to evaluate its potential in flexible sensing applications.
