A NON-INVASIVE SYSTEM AND METHOD FOR MEASURING SKIN HYDRATION OF A SUBJECT

摘要

A non- invasive system and method for measuring skin hydration of a subject comprising a thermistor (7) used in transient mode to obtain a measurement of the thermal conductivity of the skin of the subject and a processor (8) for determining a skin hydration value from the thermal conductivity measurement. The system for measuring skin hydration may be comprised in a non-invasive system for detecting blood analyte concentration, preferably glucose, including a spectroscopic device having e.g. an infrared source (2) which generates infrared beam (3) and detector (6) for detecting transmitted radiation through portion 1 (e.g. finger) of a subject. The system may also include skin hydrator (9) which moisturises the skin connected in a control loop to the system for measuring skin hydration. The system for detecting blood analyte concentration may include a photoacoustic device or a metabolic heat conformation device.
