This project explores the development of biodegradable electronic circuits, an emerging solution to reduce electronic waste by integrating bio-based substrates and environmentally friendly conductive inks. Using cellulose or rice paper as the base and carbon- or graphite-based inks as conductors, students construct simple circuits capable of powering small components like LEDs. Once tested for conductivity and functionality, the circuits are placed in soil or water to observe their natural degradation, linking hands-on electronics with sustainability concepts.
 
The analysis emphasizes the trade-offs between conductivity, durability, and biodegradability, while optimization explores improving ink formulations, substrate strength, and eco-friendly component integration. By connecting electrical performance with decomposition studies, this experiment introduces the concept of circular economy innovation in electronics, providing insight into how temporary, low-impact devices could play a role in future sustainable technology.
