June 3, Printed Electronics World: Imagine a fabric that will keep your body at a comfortable temperature—regardless of how hot or cold it actually is. That’s the goal of an engineering project at the University of California, San Diego, funded with a $2.6m grant from the U.S. Department of Energy’s Advanced Research Projects Agency – Energy (ARPA-E). Wearing this smart fabric, powered by printable electronics components, could potentially reduce heating and air conditioning bills for buildings and homes.
