There is a growing need for a conductive paste that supports non-invasive diagnostics and therapeutic monitoring in biomedical applications. The Food-based Nano Conductive Paste (FN-CoP), introduced in this study, represents an innovative solution that bridges the fields of food science and electronics. This paste, derived from natural food sources, like activated carbon and mixed with edible solvents and vegetarian-friendly binders, provides a sustainable and safe material for ingestible and edible electronic sensors and energy harvesters. FN-CoP is designed to address challenges of stability, conductivity, biocompatibility, and food safety, offering a conductive structure of nanosized particles (∼56 nm) that is ideal for applications in biomedical diagnostics and energy harvesting. By utilizing biodegradable conductive elements and Oral Rehydration Solution (ORS) as a solvent, this paste not only maintains high performance but also meets sustainable development goals (SDG 7) by replacing toxic components commonly found in traditional conductive pastes. The performance of the paste has been validated through internal testing and shelf-life studies, confirming its stability and functionality. This work offers a significant step forward in the development of green, food-safe materials for biomedical use, contributing to both sustainability and innovation in the field.
