Biodegradable Batteries That Fold Like Origami Introduced!
Like most of you out there, I always hated that origami class back in my school days, little did I know that someday some engineer is going to come up with the crazy idea of developing batteries that fold like origami aka the biodegradable batteries.
An engineer at the University of Binghamton, Seokheun “Sean” Choi, has discovered new ways of applying origami rather than making flowers and cranes. These small pieces of paper when combined with bacteria can produce energy.
“Dirty water has a lot of organic matter, any type of organic material can be the source of bacteria for the bacterial metabolism.” -Seokheun “Sean” Choi
So basically these batteries can be used in remote areas and underdeveloped countries where people have limited resources but they have to work there. Paper is usually available everywhere and at a very low price.
By using bacteria, these biodegradable batteries made out of paper generate current, although this is not enough to fulfill our requirements or gadgets today like our smartphones or tablets. Many scientists and engineers have chosen batteries in prevention and disease control as a key component when it comes to development of tools in remote areas.
This battery can be produced in nearly 5 cents and it is almost as large as a regular matchbox. The sewage water contains bacteria, which helps in generating some microwatts. It cannot charge electronic appliances although the current battery has things that it can be applied to.
We all know that tiny biosensors can be made out of paper, so when these batteries are paired together with biosensors they become a biologically degradable device. Choi will keep on working on this project and make such devices for the next three years.
