United States, China team explore energy harvesting

Six authors have described their work in harvesting energy in a paper titled "Ultrathin, Rollable, Paper-Based Triboelectric Nanogenerator for Acoustic Energy Harvesting and Self-Powered Sound Recording." Translation: A paper microphone may help charge your cellphone. Jacob Aron in New Scientist wrote about their work; he said one benefit of such a microphone is that it could harvest acoustic energy to top up a phone charge on the go. The team, from the Georgia Institute of Technology in the U.S. and Chongqing University and Beijing Institute of Nanoenergy and Nanosystems, Chinese Academy of Sciences, China, published their paper in ACS Nano last month.
