The invention relates to a data device for measuring the actions of human body parts, and a corresponding system of the data device. On one hand, the invention provides the data device for measuring the actions of the human body parts the data device comprises at least three types of sensors including a bending sensor, a pressure sensor and an angle sensor, wherein the bending sensor is used for detecting the bending states of the human body parts so as to acquire corresponding signals of the bending degrees of the human body parts the pressure sensor is used for judging whether the point-to-point movements among the human body parts are accurate and in place or not and measuring the point-to-point force of the human body parts according to the pressure value the angle sensor is used for detecting the angle change of the human body parts relative to a horizontal panel.
