Claims preview

1 . A biological information acquisition system comprising: a flexible electrode sheet having multiple electrodes arranged in an array, wherein the electrode sheet includes multiple unit sheets connected to each other, each of the unit sheets has a stretchable base, multiple stretchable lines formed on the stretchable base and extending parallel with each other, and the multiple electrodes each formed at one end of two or more of the multiple stretchable lines, the multiple unit sheets are arranged in a direction of arrangement of the multiple electrodes, of the stretchable lines of one of the unit sheets, the stretchable lines which do not end at the electrodes are each individually connected to the stretchable lines of another one of the unit sheets adjacent to the one of the unit sheets, the multiple unit sheets are connected to each other via junction sheets, each of the junction sheets has a stretchable junction base, multiple stretchable junction lines formed on the stretchable junction base and extending parallel with each other, and a stretchable junction cover formed on the stretchable junction lines, and the stretchable lines of the one of the unit sheets and the stretchable lines of the another one of the unit sheets are connected to each other via the stretchable junction lines, via an opening formed in the stretchable junction cover; an electrode selector that acquires an electric parameter from the multiple electrodes to determine which electrodes of the multiple electrodes are not in contact with a biological body and selects electrodes of the multiple electrodes adapted to be in contact with the biological body for acquisition of biological information based on the acquired electric parameter; and a biological information acquirer that acquires the biological information from the electrodes of the multiple electrodes selected by the electrode selector. 2 . The biological information acquisition system according to claim 1 , wherein the electrode selector selects the electrodes of the multiple electrodes, by using artificial intelligence. 3 . The biological information acquisition system according to claim 1 , wherein the electrode selector detects a change in an electrostatic capacitance as the electric parameter, determines a posture of the biological body based on the detected change, and selects the electrodes of the multiple electrodes to be used for acquisition of the biological information based on a determination result of the posture.
