Sweat Patch Diagnostics
April 9, 2019 | Terry Sharrer
Sweat is a diagnostic fluid, with varying levels of chloride, glucose, and lactate. To measure those metabolites, engineers at Northwestern University have a prototype, wearable sensor described as this: “The new device has minuscule holes at its base into which sweat naturally flows. From there, a complex network of valves and microchannels, each roughly the width of a human hair, route the sweat into tiny reservoirs. Each reservoir contains a sensor that reacts with a chemical in the sweat, such as glucose or lactate.” It transmits its data wirelessly and does not rely on a battery. MORE
