Someday, breathing through the nose could power hearing aids, pacemakers or blood glucose monitors, thanks to a discovery by a UW-Madison team. Materials science and engineering assistant professor Xudong Wang, post-doctoral researcher Chengliang Sun and graduate student Jian Shi created a tiny device that generates electricity when passed over by low-speed airflow, such as that created by respiration (breathing). The team reported its findings in the September issue of the journal Energy and Environmental Science.
