In a collaboration with the National Science and Technology Development Agency (NSTDA), Taiwan, the research team at Chulalongkorn university successfully measured the blood glucose and lactate levels from sweat. The team even received the Good Invention Award for Science and Pharmacy 2021 in Taiwan.

The blood sugar level is currently measured by drawing blood from the fingertips which bit difficult and waste a lot of money. The new method is simply a time-saver and saves the users from unnecessary stress and pain.  The Chula-NSTDA project uses a biochemically modified special yarn material that absorbs glucose. The material is sensitive to lactate enzymes and glucose.

“This special yarn transmits the obtained data to a test sheet inserted inside the smartwatch case… to compare the measurement against a standard Calibration Curve.  If the blood glucose is low, the color will be light, if high, the color will be dark, while the lactate value will appear even darker in color, “ Prof. Dr. Natnadda explained.

The method is currently being tested to prove its effectiveness under different circumstances. Later, it will be developed and evolved for real-time usage among patients and health-enthusiasts.

Moreover, Apple and Samsung are rumoured to bring the blood sugar measurement feature to their respective smartwatches this year It would be interesting to see which manufacturer launches it first.
