ELECTRICAL CAPACITANCE WEIGHT SENSOR AND BREATH/BODY-MOTION SENSOR USING THE ELECTRICAL CAPACITANCE WEIGHT SENSOR

摘要

PROBLEM TO BE SOLVED: To provide an electrical capacitance weight sensor that can precisely detect even a minor change of weight caused by motions resulting from hypopnea, polypnea, hyperpnea, apnea, etc. or body motions of a human.SOLUTION: There is provided an electrical capacitance weight sensor that can precisely detect even a minor change of weight caused by motions resulting from hypopnea, polypnea, hyperpnea, apnea, etc. or body motions of a human. The electrical capacitance weight sensor includes a pair of panel electrodes E and a panel electrode S in between, the panel electrode S having both sides covered with a dielectric sheet, and the panel electrodes E having a plurality of elastic spacers in connection with the panel electrode S and facing the sides of the panel electrode S, respectively.SELECTED DRAWING: Figure 2
