Sweat/humidity sensor

Figure 10.4 (a) Sweat rate sensor developed at the University of Pisa during the BIOTEX project, (b) Humidity sensor integrated into textile pockets of the sensing device at different distances from the skin. 

Body fluids such as sweat, urine or tears can give information about the health state of a patient and are therefore collected and analysed in medicine. Fluids or humidity in general can be measured by two distinct physical principles either by resistive or capacitive sensors.
