[The design of a new respiratory detecting system using impedance method].
A coupling principle of reflecting impedance based on resonance is designed to achieve impedance detection with high sensitivity. It is characterized by small impelled current, high sensitivity and simple circuit. The principle can be used not only in detecting human respiratory impedance, but also in detecting the bio-impedance of other human organs. It may find wide application in this aspect.
