Engineers develop bacteria-powered battery made of paper

Engineers using origami, the Japanese art of paper folding, have developed an inexpensive, bacteria-powered battery made from paper.

The engineers say the battery generates power from microbial respiration, delivering enough energy to run a paper-based biosensor.

Their researchers was reported in the Nano Energy journal.

“Paper is cheap and biodegradable and we do not need external pumps or syringes because paper can suck up a solution using capillary force” said Seokheun Choi from Binghamton University in the US.

They expect the method to be useful to anyone working in remote areas with limited resources.

Experts working on disease control and prevention have seized upon it as a key material in creating diagnostic tools for the developing world.

Choi’s battery, which folds into the size of a matchbook, uses an inexpensive air-breathing cathode created with nickel sprayed onto one side of ordinary office paper.

The anode is screen printed with carbon paints, creating a hydrophilic zone with wax boundaries.

Total cost of this potentially game-changing device is just five cents.
