Graphene has been hailed as a wonder fabric since it was first made more than a decade ago. It's showing up in an increasing number of products,including coatings, sports equipment and even light bulbs. Now scientists are one step closer to making graphene audio speakers for mobile devices. They report in the journal ACS Applied Materials & Interfaces a simple way to manufacture once-elusive thermoacoustic speakers using the ultra-thin fabric.
