Johns Hopkins University undergrads' device could save billons in health care costs

Team Aezon -- composed entirely of Johns Hopkins undergrads -- is a top 10 finalist for the Qualcomm Tricorder XPrize, a $10 million global competition to develop a portable, medical diagnostic device for the consumer market, inspired by the “tricorder” used on Star Trek. This device could help reduce the estimated $38 million wasted annually in unnecessary emergency department visits, says Kenney Scholar Ryan Walter, Engr '16, who cites research from the New England Healthcare Institute and Truven Health Analytics.
