sEMG database of the MYO bracelet for hand gestures

The data were collected with the MYO armband for four different hand movements: fist, cylindrical grip, spherical grip and tip pinch. 225 tests were obtained from different users for each movement and a total of 900 tests for the four movements. Each Prueba*** file corresponds to a different person. The age range is 20 to 45 years of the male and female gender. Each of the tests contains 9 different attributes. The first eight columns correspond to each of the sEMG sensors, column 9 contains sampling time information. Each test includes 998 samples per sensor. The total time sampled was 5 seconds for each movement.本数据集依托MYO臂带（MYO armband）采集得到，涵盖四类手部动作：握拳、柱状握姿、球状握姿以及指尖捏合。针对每类动作，共完成来自不同受试者的225次测试，四类动作累计总计900次测试样本。每个Prueba文件对应一名独立受试者。参与测试的受试者年龄分布在20至45岁区间，涵盖男性与女性群体。单次测试包含9项不同属性：前8列为各表面肌电（surface electromyography, sEMG）传感器的采集数据，第9列存储采样时间信息。每类传感器在单次测试中包含998个采样点，单类动作的总采样时长为5秒。
