Charge phone battery by motion-powered fabric
London: Scientists at the Sungkyunkwan University.South Korea have created a double-layered fabric out of silver-coated woven textile that can charge the battery of a mobile phone.
The foldable patch of fabric wrapped around you wrist can gather enough energy from your arm movement.
The new fabric relies on the triboelectric effect,which occurs with certain materials become electrically charged after coming into fricative contact with a different material.
Electrons are transferred from one material to the other,causing one material to build up a positive charge,while the other gets a negitive charge
