Breath acetone is biomarker of diabetes and for a healthy person the concentration remains within 1 ppm. Higher concentration of acetone in exhale breath indicates the tendency of diabetes. Determination of breath acetone using gas sensor could be an alternative of detection / monitoring of diabetes. Functional Materials and Devices Division over the years has created a niche in developing chemiresistive based sensor for different gases and VOCs detection in ppm levels. Recently novel chemiresistive sensing materials have been been successfully developed and a prototype device for detection of exhale breath acetone; biomarker of diabetes has been fabricated. Laboratory label performance verification in real breath was satisfactory.
