One of the most consistent pieces of advice from health organizations about COVID-19 has been that everyone do their utmost to limit contact with people who may have been exposed to the novel coronavirus that causes the disease. That’s difficult in a hospital setting, where medical professionals regularly have to take patient vital sign measurements in order to provide proper care. But a new collaborative effort by MIT, Brigham and Women’s Hospital, Boston Dynamics and others might provide a way to get those measurements without putting front-line healthcare workers directly in harms’ way.
