It is the paper-based bacteria-powered battery design is part of a new field of research called papertronics. It is a fusion of paper and electronics. US-based scientists have developed a bacteria-powered battery (bio-battery) on a single sheet of paper. It is capable of powering disposable electronics.

Bio Battery

  • In this battery researchers had laid ribbon of silver nitrate on a piece of chromatography paper.
  • On top of this, scientists had placed thin layer of wax to create a cathode (positive electrode).   
  • On the other side of the paper, reservoir out of a conductive polymer was made which acts an anode (negative electrode) filled with a few drops of the bacteria-containing wastewater liquid.   
  • When the paper is folded so that the cathode and anode come into contact, it is powered by the bacterial metabolism.
  • This process is also known as cellular respiration.

Benefits

  • This bio-battery is cheap and can be easily manufactured as power source for medical sensors in remote and developing areas.
  • In this case, the power is generated by common bacteria found in wastewater.
  • It can store power generated by organic compounds.
  • The simple components are needed to make these kinds of paper-based batteries.
  • This makes them a reliable backup in places where grid electricity or conventional batteries aren’t available.
