Abstract:
1. A bioelectrical information acquisition device comprising: three or more electrodes including a plurality of biomedical electrodes attached to a skin surface of a person to be measured for monitoring a bioelectrical information, the bioelectrical information generated along with biological activities of the person; an acquisition section for acquiring the monitored bioelectrical information; a resistance measuring section for setting a plurality of electrode pairs, each pair constituted by two electrodes of the three or more electrodes and measuring at least one of an electrical impedance value and a resistance value between two electrodes forming each of the electrode pairs, an attachment state judging section for judging an attachment state of each of the electrode pairs, by comparing the impedance value or the resistance value measured by the resistance measuring section, with a predetermined range of numeric values; and an inappropriate electrode identifying section for identifying an electrode in an inappropriate attachment state from the plurality of electrode pairs based on the attachment state of each of the plurality of electrode pairs, the attachment state judged by attachment state judging section; and a notification section for notifying the person to be measured of the electrode in the inappropriate attachment state identified by the inappropriate electrode identifying section, wherein the notification section is configured to give an electrical stimulus from each electrode of specified electrode pairs to the skin surface of the person to be measured by applying a voltage to each electrode of the specified electrode pairs, the specified electrode pairs determined in accordance with the electrode in the inappropriate attachment state identified by the inappropriate electrode identifying section, to thereby notify the person to be measured of an electrode from which the electrical stimulus has not been given to the skin surface of the person as the electrode in the inappropriate attachment state.
