2. HYPOTHESIS AND OBJECTIVES In the proposed method of sensing the vital health sign related to CVDs, thermal heat transfer performance of the skin will be evaluated using a non-contact based IR temperature sensor. The temperature of the skin is significantly dependent upon the heat source as blood vessels (veins and capillaries) in the vicinity of the skin. However, there are several locations in the human body, where arteries are also at a relatively less depth from the outer skin surface (radial or ulnar arteries at the wrist and carotid artery in the neck). In any scenario, if it is possible to track the flow of blood from the thermal performance of the skin, then it could be useful in predicting various states of the human health related to cardiovascular activities.
