Large-area grid type epidermal electronic system for closed-loop man-machine interaction

The invention belongs to the field of epidermal electronics, and discloses a large-area grid type epidermal electronic system for closed-loop man-machine interaction. The large-area grid type epidermal electronic system comprises epidermal myoelectricity electrode arrays, a joint rotation angle sensor array, an electric touch sensation sensor array, connecting structures and a circuit compensation structure, wherein the epidermal myoelectricity electrode arrays are used for collecting myoelectricity signals of the internal muscles and the external muscles of all fingers and the muscles of a wrist; the joint rotation angle sensor array is used for collecting the rotation angles of finger joints and the wrist; the electric touch sensation sensor array is used for stimulating fingertips through an electric current and a voltage; the circuit compensation structure is used for eliminating excess myoelectricity signals introduced by each epidermal myoelectricity electrode connecting structure, so that the accuracy of obtained signals of man-machine interaction equipment is guaranteed. Each sensor of the system is very light, thin and small, has stretchability and conforms with the mechanical property of skin, and at the same time, the problem that heat dissipation and perspiration can not normally proceed due to large-area covering is solved.
