The Nano technology fabric can harvest energy from motion could one day lead to clothing that can power portable electronics through Piezoelectric effect.
At Georgia Institute of Technology Zhong Lin Wang designed the new fabric based on a phenomenon called the piezoelectric effect. This effect occurs when mechanical pressure is applied to piezoelectric materials it causes a small electric charge.
“The fiber-based nano generator would be a simple and economical way to harvest energy from physical movement,” Wang said. “If we can combine many of these fibers in double or triple layers in clothing, we could provide a wearable power source that would allow people to generate electrical current even while walking.”
“If the two fibers scrub together the piezoelectric semiconductor process converts the mechanical motion into electrical energy,” Wang explained. Wang and colleagues Xudong Wang and Yong Qin have made many fiber nano generators which are tested on an apparatus that uses a spring and wheel to move the fibers against one another.
Let’s hope the technology comes to the markets soon for us to use.
