Chinese team reports breakthrough in power-generating yarn
Researchers at Shanghai’s Donghua University have found a way to achieve the continuous and scalable manufacture of amphibious energy yarns and textiles that are composed of elastic polymers (rubber) and spiral metal fibres, the two of which produce an electro-transfer reaction during any deformation before generating power. This could lead to smart clothing.
The team of researchers published a paper, titled ‘Continuous and Scalable Manufacture of Amphibious Energy Yarns and Textiles’ in ‘Nature Communications’ in February.
With the help of core-sheath structure and gain-coupled power generation mechanism, the researchers found that the amphibious energy yarns and textiles can be self-generating without interaction with other objects, and can be used in various situations, even in liquids.
Power-generating yarns can also be woven with other fibers, such as nylon fiber and polyacrylonitrile fibers, so that the breathability, comfort level and power generation of textiles can be effectively controlled. (DS)
