A Face Mask to Detect Kidney Disease

Surgical face masks help prevent the spread of airborne pathogens and therefore were ubiquitous during the COVID-19 pandemic. Now, a modified mask could also protect a wearer by detecting health conditions, including chronic kidney disease. Researchers reporting in ACS Sensors incorporated a specialized breath sensor within the fabric of a face mask to detect metabolites associated with the disease. In initial tests, the sensor correctly identified people with the condition most of the time.
