The ubiquitous microbes are in our bodies, in soil, in water, in garbage and in the air. In order to fill their stomachs, they collect electrons from the environment and then excrete them. 
Many scientists have found ways to capture these electrons and turn them into power supplies. But Seokheun "Sean" Choi, an assistant professor at the Bioelectronics and Microsystems Laboratory at the State University of New York, said they have found ways to do it with paper.
His collapsible paper battery is a biofuel cell that can support the operation of small biosensors. Since it is made of paper, the equipment is inexpensive and easy to handle. Because its power generation material is microbe, it can produce electricity whenever and wherever it is used.
Choi said: "In theory, microbes are everywhere. I even think that bacterial batteries can be used in resource-constrained environments."
This means you can use it in disaster areas, battlefields or in clinics in poor areas.
Fundamentally, Choi's bio-battery has two main components: an anode and a cathode. The anode is typically a source of electrons that form a current that flows toward the cathode.
In this battery, Choi places the anode on one side of the paper, which is filled with microorganisms and placed in a container filled with conductive polymer. The other side of the paper is the cathode, which is coated with a thin layer of wax, and under the thin wax is a band of silver nitrate.
By folding the paper and contacting the two poles, electrons in the microorganisms are released from the positive electrode to form an electric current. The way the paper is folded is different, and the current output is not too good. For example, in the shape of an accordion, microorganisms are brought into contact with each other six times to form a current of 44.85 microwatts of 105.89 microamperes.
Choi admits that there is very little energy produced. In the early days of his research, he first suspected that these products could be used when developing paper electronics. Later, when he realized that biosensors used to detect pathogens or monitor blood sugar levels did not require much energy.
He said: "Now, this battery uses waste water, but this battery can use any liquid, such as blood, sweat, urine, saliva."
This is not the first paper battery developed by Choi. Earlier this year, his team proposed a battery modeled as a ninja star.
And now this paper battery is an upgraded version. He said: "This is an upgraded version. You don't need a lot of layers of paper. All the parts are concentrated on one piece of paper."
