New wearable sensor can analyse your sweat for disease

Washington

US researchers have developed a wristband-type wearable sweat sensor that could help diagnose cystic fibrosis, diabetes and other diseases.

The sensor collects sweat, measures its molecular constituents and then electronically transmits the results for analysis and diagnostics through a smartphone, Xinhua News Agency reported. Unlike previous sweat collectors, the new device does not require patients to sit still for a long time while it collects sweat from them. The wearable device is a two-part system of flexible sensors and microprocessors that sticks to the skin, stimulates the sweat glands and then detects the presence of different molecules and ions based on their electrical signals.
