. The hi-tech yarns, also known as ‘twistrons’, produce electricity which can power wearable health devices and smart clothes.
Carbon yarns are made from carbon nanotubes. The scientists twist the carbon nanotubes to form lightweight, high in strength yarns.
Once the yarn or twistron energy harvester is stretched, it generates electricity.
A normal capacitor is charged by an external energy source, such as a battery, but in the case of carbon nanotube yarns, the yarns can be charged directly by submerging it into an electrolyte.
This yarn could also be used for harvesting electricity from the ocean by converting the motion of the waves into electrical energy. The salty water of the ocean acted as the electrolyte. Enormous amounts of electricity can be harvested from the ocean waves using this technology.
