Patent ID: 8668653

Claim:
A sheet for measuring biological information formed of a nonconductive material having elasticity so as to fit on the upper body of an examinee, the sheet being characterized in having respiratory information measuring sensors, each of said sensors including a conductive member varying its electric resistance according to variation of constitution of the examinee through breathing thereof under a turning-on-electricity state and capable of delivering electric information based on the variation of electric potential to a respiratory information analysis device, wherein: a portion of the plurality of respiratory information measuring sensors is disposed at a perimeter of a chest region and another portion of the plurality of respiratory information measuring sensors is disposed at a perimeter of an abdominal region of the garment, electric resistance of the plurality of respiratory information measuring sensors varies with expansion and contraction of one of the length and cross-section of the conductive member in response to the examinee's breathing, the conductive member of each of the respective plurality of respiratory information measuring sensors is arranged at either a position winding around a chest region of the examinee and a position winding around an abdominal region of the examinee, the respiratory information analysis device selects at least one output of at least one sensor in the chest region and the abdominal region based on the amplitude of output of these sensors, and the output of the selected sensors is used for anal sis and the output of unselected sensor is not used for analysis.
