| Abstract: | A coupling principle of reflect impedance based on resonance is designed to achieve impedance detecting of high sensitivity. It has some attractive features as small impel current, high sensitivity and simple circuit. The principle can replace the current detecting method of organism impedance, and offer a safe and reliable tool for human body impedance detecting and tomography. It is expected that the system will gain wider use in reality. |
