Multifunctional component made from unique hydrogel electrolyte embedded with water-soluble photoluminescent quantum dots

Scientists in Hong Kong and China have combined a semi-transparent arrangement of anodes and cathodes with a transparent electrolyte to make the first ever photoluminescent microbattery that can simultaneously act as a power supply and a full-colour display.
