In the figure, 1 is a disc-shaped substrate made of elastic plastic or metal, and 2 is the upper surface of the substrate l. The strain gauge 3 affixed to the strain gauge 3 is a coating material that covers the strain gauge 2, and has an elastic protrusion 4 at the center. 5
is a lead wire connected to the strain gauge 2.

である。2 and 3 show an embodiment of the respiration change detection device according to the present invention, in which the respiration detection sensor S as described above is placed under the sheets of a bed pad or mattress 6 as shown in FIG. As shown in FIG. 3, the signal output from each sensor S is amplified by an amplifier 7, and a filter 8 cuts a direct current component and cants noise, thereby reducing the variation component. The outputs are added by an adder circuit 9.

大きな信号レベルとして得ることができる。By arranging the breathing detection sensors S in a matrix in this way, breathing can be detected without being affected by differences in body position during sleep, and the output of each sensor S can be summed up. Therefore, even if the change component of each sensor S due to respiration is small, it can be obtained as a large signal level.
