BIOLOGICAL SIGNAL MEASURING SENSOR AND APPARATUS FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a biological signal measuring sensor which can be put on the skin unrestrictedly because of its high flexibility and which can efficiently acquire pieces of signal information not only those based on pressure fluctuation such as the cardiac sound or the respiratory sound but also those based on bioelectricity such as the heart potential or the muscle potential with a simple configuration inexpensively, and also to provide a measuring apparatus using the same.

SOLUTION: The biological signal measuring sensor comprises a first bioelectrode 2 made of a first piezoelectric polymer film 7a sandwiched between a first conductive fabric 6a and a second conductive fabric 6b, a second bioelectric electrode 3 made of a second piezoelectric polymer film 7b sandwiched between a third conductive fabric 10a and a fourth conductive fabric 10b, a first pair of electrical signal lines 8a and 8b for measuring the pressure fluctuation, and a second pair of electrical signal lines 11a and 11b for measuring the bioelectricity.
