Nature (Jan. 27) -- “Until now, sweat sensors have typically involved patches that are removed for subsequent chemical analysis by separate, nonwearable machines,” says John Rogers, a professor of materials science and engineering at Illinois. Rogers is developing wearable electronics that detect sweat and measure other bodily functions. “The current device is wearable, it provides continuous data streams, and it measures multiple biomarkers simultaneously.” Also: Science (Jan. 27), Los Angeles Times (Jan. 27), ASEE FirstBell (Jan. 28).
