Specialists from the University of California at San Diego have developed batteries that can be applied to fabric by printing. The new battery was stretchy and flexible. During the development demonstration, the researchers applied the battery to the T-shirt and used it to operate a green LED, Techxplore reports.
In order for the battery to be stretched, an elastic polymer material made of isoprene was added to the composition. The new battery can be increased in any direction at a rate of two times without damage.
For the manufacture of ink, experts have used zinc oxide, silver oxide and an additive from the above polymer. Scientists have also added bismuth oxide so that the battery can be recharged.
