Nori seaweed, almonds, and 24-carat edible gold leaves are among the "ingredients" used to create the world's first edible rechargeable battery, which was listed by Time magazine among the best inventions of 2023. It was developed by the Italian Institute of Technology.

Currently, the battery can recharge small devices like LED lights, but in the future, it could help "monitor our health" by powering smart pills, said engineer Mario Caironi, who led the team that created the first edible accumulator, in an interview with Il Messaggero.
