The project proposes the creation of a wearable chemical device in the form of a simple patch, bracelet or pendant, designed for sweat collection and chemical analysis; it integrates an electronic wireless communication systems in direct contact with the skin (NFC technology).
The patch is a device for monitoring and diagnosing patients’ or sportsmen’ s health.
The user -after placing his/her smartphone in connection with the patch- selects the region to be subjected to colorimetric analysis; the result is obtained as RGB color, which, appropriately elaborated, leads to the quantitative evaluation of the marker analyzed in this region (chloride, glucose, pH, sodium ions, etc.).
