Fig. 3: Characterization of the motion capture module of the EEN for motion monitoring.

a Gait cycle of three joints when walking at 4 km/h captured by the motion capture module of the electronic exoneuron and optical motion capture system. b Real-time monitoring of the racewalking of the athlete by the EEN applied on the skin. c Adhesive force before and after exercise. d Stability comparison of EEN and IMU methods for capturing the motion of lower limbs from slow walking to running. e Coefficient of variation of three joints during the motion of lower limbs captured by the EEN method. f Coefficient of variation of three joints during the motion of lower limbs captured by the IMU method. g Drift effect comparison of EEN and IMU methods
