Austrian and Japanese researchers on Wednesday unveiled solar cells thinner than a thread of spider silk that are flexible enough to be wrapped around a single human hair.
“You could attach the device to your clothes like a badge to collect electricity (from the sun)… Elderly people who might want to wear sensors to monitor their health would not need to carry around batteries,” Sekitani told AFP.
“Power generation by solar cells increases with their size. As this device is soft, it is less prone to damage by bending even if it gets bigger,” he said.
