New fabric can harvest energy from sun and wind
30/09/2016
The researchers at the US institution used a commercial textile machine to weave together solar cells constructed from lightweight polymer fibres and fibre-based triboelectric nanogenerators. The generators use a combination of friction and electrostatic induction to generate small amounts of electrical power from motion such as rotation, sliding and vibration.
Zhong Lin Wang, a Regents professor in the Georgia Tech School of Materials Science and Engineering, believes the fabric could be combined with wool for use in tents, curtains or wearable garments.
“The backbone of the textile is made of commonly-used polymer materials that are inexpensive to make and environmentally friendly,” Mr Wang said. “The electrodes are also made through a low-cost process, which makes it possible to use large-scale manufacturing.”
Early tests of the fabric have shown that it can withstand repeated, rigorous use; the researchers are now searching for ways to further increase its durability. Future efforts will also go into optimising the fibre for industrial use, including taking steps to ensure the electrical components are shielded from rain and moisture.
