PROBLEM TO BE SOLVED: To dispose a human body detection apparatus in lightweight, flexible bedding and make it possible to detect the positions of a human body in both width and length directions of the bedding.SOLUTION: If a capacitance Cbetween the power source side wire Hand the ground side wire composing a parallel two-wire line of laterally extending three parallel two-wire lines H(n=1 to 3) exhibits a variation &Dgr;Cof a larger value compared with the basic capacitance Cwhich is a capacitance with no human body resting, it is understood that a human body 101 is resting on the power source side wire H. Also, if a capacitance Cbetween the power source side wire Hand the ground side wire composing a parallel two-wire line of longitudinally extending three parallel two-wire lines H(m=1 to 3) exhibits a variation &Dgr;Cof a larger value compared with the basic capacitance Cwhich is a capacitance with no human body resting, it is understood that a human body 101 is resting on the power source side wire H. |
