Fig. 6: PVA-EBPD hydrogel sensor for limb joint and TMJ activity monitoring in pigs.

a Schematic diagram of the PVA-EBPD hydrogel sensor adhered to the elbow, knee, ankle joints, and TMJ of a pig to monitor the joint movements. b–e Passive motion sensing lines of the elbow (b), knee (c and d), and ankle (e) joints. f–h Active motion, including walk (f), squat (g), and turn round (h) sensing lines of the right ankle joint in real scenarios. i–k Bilateral TMJ passive opening and closing mouth (i), lateral movement to the left and right sides (j), protrusion and retrusion (k) sensing map lines. l–n Sensorimotor maps for active possible tapping movement (l), eating (m), and eating with head-turning (n). (The red arrows in f represent the position of PVA-EBPD hydrogel sensor adhesion). Source data are provided as a Source Data file.
