WyoFlex Dataset

A dataset named WyoFlex sEMG hand gesture, which contains surface electromyography (sEMG) signals acquired from the forearm with a sampling frequency of 1000 Hz. For this, were recorded the data of 28 participants between 18 and 37 years old without neuromuscular disease or cardiovascular problems. The test protocol consisted of sMEG signals acquisition corresponding to ten wrist and grasping movements (extension, flexion, ulnar deviation, radial deviation, hook grip, power grip, spherical grip, precision grip, lateral grip, and pinch grip), considering three repetitions for each gesture. Likewise, the implemented acquisition system consists of a portable armband with four sEMG channels distributed equidistantly for each forearm. The database could be used for recognition of hand gestures, evaluation of the evolution of patients in rehabilitation processes, control of upper limb prostheses and orthoses, and biomechanical analysis of the forearm.
