A biosignal measurement and electrical stimulation device, comprising: a pad in which a plurality of horizontal electrical wires (A1-A6, An) and vertical electrical wires (B1-B6, Bn) for electrical stimulation are formed to intersect; and a control module that is electrically connected to the pad to acquire body state information of a patient by measuring a biosignal of intersections (A1B1, A1B2...A6B6) between the horizontal electrical wires (A1-A6, An) and the vertical electrical wires (B1-B6, Bn), and that enables generation of electrical stimulation while controlling power that is supplied to the horizontal electrical wires and the vertical electrical wires using the body state information, characterized in that said plurality of horizontal electrical wires (A1-A6, An) and vertical electrical wires (B1-B6, Bn) are orthogonal to each other and are each disposed in said pad with a predetermined gap therebetween so as to form a grid-like configuration, and in that said control module includes a first switch module which is connected to the horizontal electrical wires (A1-A6,An), and a second switch module connected to the vertical electrical wires (B1-B6, Bn), and a controller, said first and second switch modules (142, 144) being respectively configured to control on/off power that is applied to each horizontal, respectively vertical electrical wire, and the controller being configured to control the fisrt and second switch modules to perform a function of controlling entire operation of the device, wherein said entire operation controlling function comprises controlling the first switch module to turn on power on a first horizontal wire and therefafter sequentially turning on the second switch module to power the vertical wires from a first vertical wire to a last vertical wire while power applied to the first horizontal wire is on, and repeating said operations for each horizontal wire (A2-An) until a biosignal associated with each intersection is obtained, thereby forming a random measurement electrode for measuring a biosignal. a pad in which a plurality of horizontal electrical wires (A1-A6, An) and vertical electrical wires (B1-B6, Bn) for electrical stimulation are formed to intersect; and a control module that is electrically connected to the pad to acquire body state information of a patient by measuring a biosignal of intersections (A1B1, A1B2...A6B6) between the horizontal electrical wires (A1-A6, An) and the vertical electrical wires (B1-B6, Bn), and that enables generation of electrical stimulation while controlling power that is supplied to the horizontal electrical wires and the vertical electrical wires using the body state information, characterized in that said plurality of horizontal electrical wires (A1-A6, An) and vertical electrical wires (B1-B6, Bn) are orthogonal to each other and are each disposed in said pad with a predetermined gap therebetween so as to form a grid-like configuration, and in that said control module includes a first switch module which is connected to the horizontal electrical wires (A1-A6,An), and a second switch module connected to the vertical electrical wires (B1-B6, Bn), and a controller, said first and second switch modules (142, 144) being respectively configured to control on/off power that is applied to each horizontal, respectively vertical electrical wire, and the controller being configured to control the fisrt and second switch modules to perform a function of controlling entire operation of the device, wherein said entire operation controlling function comprises controlling the first switch module to turn on power on a first horizontal wire and therefafter sequentially turning on the second switch module to power the vertical wires from a first vertical wire to a last vertical wire while power applied to the first horizontal wire is on, and repeating said operations for each horizontal wire (A2-An) until a biosignal associated with each intersection is obtained, thereby forming a random measurement electrode for measuring a biosignal.
