Exhaled human breath is rich with bio-molecules. Some are vital bio-markers for diseases. Exhaled Acetone is related to the glucose level in our blood stream and hence it is a good bio-marker for diabetes. Diabetes is generally diagnosed invasively by measuring blood glucose concentration. Above certain concentrations the person is diagnosed to have diabetes, and below that the person will has a normal sugar. In this project we are fabricating MEMS devices and coat them with a sensitive and selective layer to acetone for non-invasive screening of diabetes from exhaled breath.
