Not only sunlight, even your footsteps can be converted into usable electricity
Since a long time, the world has been going gaga over the benefits of generating
This research, which was published in the
According to the research team, “When the nanofibers are embedded within flooring, they're able to produce electricity that can be harnessed to power lights or charge batteries. And because wood pulp is a cheap, abundant and renewable waste product of several industries, flooring that incorporates the new technology could be as affordable as conventional materials.”
It must be noted that chemically treated cellulose nanofibers are a simple, low-cost, and effective alternative for harnessing this broadly existing mechanical energy source, said Xudong Wang, an associate professor of materials science and
The UW-Madison team's advance is the latest in a green energy research field called "
The researchers revealed that each functional portion inside such flooring has two differently charged materials -- including the cellulose nanofibers, and would be a millimeter or less thick. The floor could include several layers of the functional unit for higher energy output.
"So once we put these two materials together, electrons move from one to another based on their different electron affinity. The electron transfer creates a charge imbalance that naturally wants to right itself but as the electrons return, they pass through an external circuit. The energy that process creates is the end result of TENGs,” added Wang.
We are sure that this technique of generating electricity would not be cheap but also durable.
