Tamil Nadu: Scientists Develop Affordable Wearable Sensor That Removes Necessity For Invasive Tests by Swarajya Staff - Mar 17, 2021 10:22 AM Dr Vinu Mohan in his lab (PIB) Dr Vinu Mohan, a recipient of the INSPIRE Faculty Fellowship instituted by the Department of Science and Technology, has developed a flexible low cost, wearable sensor that can track sweat for monitoring the health and physiological status of the human body. It can obviate the necessity of blood and other invasive tests. The wearable microfluidic sensor, which does not need a clean room, can be used for in situ monitoring of biomarkers such as lactate, Sodium (Na+), Potassium (K+), and Alkaline/acidic nature (pH) simultaneously from sweat samples.
