Scientists Develop Edible Paper Battery For Medical Devices

Researchers from a European university have created a fully edible paper battery that can power tiny medical sensors inside the human body. The battery uses natural materials like cellulose and food-grade minerals, with no toxic heavy metals. Once it finishes working, it can safely dissolve inside the digestive tract like food.

The device is thin, flexible, and produces low voltage. It can supply power for ingestible capsules used to check stomach and intestinal health. Scientists say the invention will cut the risk of surgery to retrieve implanted small medical devices. The team is now testing longer working time and larger power output, aiming to commercialize the technology within 5 years.
