The study focuses on the development and use of graphene/PEDOT: PSS composite sponge-based sensors. Currently, there is a demand for low-cost, printable sensors that may be used in a variety of strain-induced applications. Graphene and PEDOT: PSS have both demonstrated outstanding sensing capabilities, given their improved electrical and mechanical characteristics. The conjugation of two nanomaterials to construct efficient, sensitive, and flexible sensors is demonstrated here. Prototypes were characterized for their electrical performance under mechanical deformation. The findings presented here provide a foundation for the sensors to be employed in real-Time strain-sensing applications.
