A two-in-one solar bio battery and solar panel has been created by researchers at Imperial College London, UK, who printed living cyanobacteria and circuitry onto wallpaper. Cyanobacteria are photosynthetic microorganisms that have been on Earth for billions of years, and are thought to be the primary reason why the Earth’s atmosphere is oxygen rich. The team of researchers demonstrated that cyanobacteria could be used as an ink and printed from an inkjet printer in precise patterns onto electrically conductive carbon nanotubes, which were also inkjet-printed onto the piece of paper. It showed that the cyanobacteria survived the printing process and…
