This project designs smart bandages using recycled and sustainable materials. PET bottles are turned into strong mesh fibers, and plastic containers become waterproof layers.Old textiles form absorbent cores, while organic cotton waste creates soft contact layers. Biodegradable polymers like PLA serve as eco-friendly structural elements. Miniaturized sensors track temperature, humidity, and detect infection via pH or conductivity changes. Reused electronics from discarded devices reduce e-waste. BLE modules transmit data wirelessly for real-time health monitoring. The project merges environmental sustainability with advanced healthcare.
