On-body test of the multifunctional e-textile skin ulcer sensor. (a) Optical images of the multifunctional e-textile skin ulcer sensor after mounting on the body, a snapshot of a real-time communicating smartphone application, and the signals from the sensor over 5 min. (b) The sensors were continuously tested on multiple sites, including the forearm, elbow, and heel. Using three samples, the (c) P, (d) T, and (e) Z of the skin were measured from multiple sites. On the heel site, P, T, and Z were tested with five subjects. (f) The relationship between the P values and the subjects’ body weight was assessed. (g) The T values were compared to the T values measured by a thermocouple. (h) The Z values were measured using frequencies of 0.1 kHz and 10 kHz.
