A full-head mannequin testing wireless performance in Notre Dame’s anechoic chamber for the Wireless Institute
A yellow mannequin half-head sits on a desk in Bert Hochwald’s electrical engineering lab with a dissected cell phone rubber banded to its ear. On a nearby computer screen, colored lights reveal the electromagnetic radiation the phone projects into the half-head, which was specially made to mimic the flesh and fluids of a real human being.
Hochwald, the Freimann Chair professor at the Notre Dame Wireless Institute, and his team are leading a three-year, $1.2 million investigation into how to improve the performance of cell phones while also reducing the potentially harmful radiation the phones expose our bodies to.
