Researchers say they have developed a battery that can stretch and bend without losing power, a discovery that could open the door to wearable technology, smart medical devices and robots with human-like movements.
“The texture is a bit like toothpaste,” senior author Aiman Rahmanudin, an associate professor at Linköping University in Sweden, said in a statement. “The material could, for example, be used in a 3D printer to shape the battery into the desired shape. This opens up new horizons for technology.”
Traditional batteries face a trade-off between size/flexibility and power. Scientists at Linköping University’s Organic Electronics Laboratory have found a solution to this problem using materials that can hold and conduct both negative and positive charges to power devices, regardless of their energy requirements. The results were published April 11 in the journal Science Advances.
