Fig. 8: Multifunctional device for sports rehabilitation medical.

a Schematic illustration showing an integrated multifunctional sensing system (sensing, heat treatment and sterilization) for sports rehabilitation. Resistance variation of PMPPF sensors when monitor large body deformation, such as b wrist and c fingers bend. Insets: digital images of the wrist and index finger at different angles. Resistance variation of PMPPF sensors when monitor small body deformation, such as d fisting, e swallow, f mouth open/close and g blowing. Insets: digital images of different stages of fist clenched, swallow, mouth and blowing. IR images of PMPPF sensor under infrared light at 50 °C for hot application on the h wrist, i elbow, j neck.
