The StethoCloud system can diagnose pneumonia with a stethoscope, a tiny custom mic, and a smartphone. It could save hundreds of thousands of lives.
The StethoCloud is the creation of four students from the University of Melbourne—Hon Weng Chong, Kim Ramchen, Mahsa Salehi, and Andrew Lin—for Microsoft's student innovation competition, the Imagine Cup. The project won Microsoft Australia's national Imagine Cup and placed in the worldwide finals. Two of the team members, Chong and Lin, have a medical school background and have interned in developing nations. After a conversation about pneumonia with his mentor at the university, global health expert Dr. Jim Black, Chong spent two weeks in February developing a prototype. "The first one I was like, 'why aren’t we getting any sounds?'" says Chong, "and the next one, we were getting all this extra noise so we kept refining it."
