Digital semeiotics is one of the newest recent challenges for assessing a number of computational
descriptors to atherosclerotic cardiovascular diseases that are leading causes of mortality worldwide. These descriptors can be expressed involving (i) morphometric, biometrics and colorimetric of the face; (ii)spectroscopic analysis of skin and iris, of sub-cutaneous substances and the function of subcutaneous
tissues, and (iii) compositional analysis of breath and exhaled. In this work, we describe the design and functionality of the first prototype of Wize Sniffer (WS: "Wize Sniffer 1.0", a new portable device for breath analysis limited to an effective number of substances. Within the european SEMEOTICON Project, by the WS, we intend a hardware/software tool for both the analysis of volatile organic compounds of breath and a platform for data mining and data integration. The WS should be able to provide useful information about the “breathprint”, i.e., the analog of fingerprint for the state of health of an individual.
