An
upper limb wearable device includes an
elbow fitting, an upper arm fitting extending from one end of the
elbow fitting, an upper arm strap movably connected to the upper arm fitting, a lower arm fitting extending from the other end of the
elbow fitting, a lower arm strap movably connected to the lower arm fitting, a
wrist strap extending from one end of the lower arm fitting, and position-adjustable upper arm
electromyography sensing modules and lower arm
electromyography sensing modules. After the
upper limb wearable device is worn on the
upper limb of a user, first and second differential
electrode assemblies of the upper arm
electromyography sensing modules are respectively located on a pair of upper arm antagonistic muscles, and third and fourth differential
electrode assemblies of the lower arm electromyography sensing modules are respectively located on a pair of lower arm antagonistic muscles. The upper limb wearable device enables the user to adjust the positions of the electromyography sensors by himself, so that the electromyography sensors can be arranged at correct positions, and thus the accuracy of
motion analysis is improved.
