Scientists say they’ve created a battery that can stretch and bend without losing power. The discovery paves the way for wearable technology, smart medical devices, and robots with human-like movements.
“The texture is a bit like toothpaste,” senior author Aiman Rahmanudin, an assistant professor at Linköping University in Sweden, said in a statement. “The material can, for instance, be used in a 3D printer to shape the battery as you please. This opens up for a new type of technology.”
Traditional batteries face a tradeoff between size/flexibility and power. The scientists at Linköping University’s Laboratory of Organic Electronics solved that problem by using materials that can hold and conduct negative and positive charges to power devices regardless of their energy demands. The findings were published April 11 in the journal Science Advances.
