    In this paper, the sensing based on electromagnetic resonant coupling and its applications are discussed. Here, the electromagnetic resonant coupling is defined as the composite phenomenon of electromagnetic coupling and double resonance. We proposed a method estimating the two state quantities strength of electromagnetic coupling and double resonance by measuring the reflection coefficient which is equivalent to the ratio of traveling wave to reflected wave. The method to estimate the strength of electromagnetic coupling is called coupling sensing and the method to estimate the strength of double resonance is called double resonance sensing, respectively. The reason why measurement is done in transmitter is that the additional device for receiver is not required which is the large advantage in application. As the application of coupling sensing, battery-less position sensor is proposed. The sensor is based on the fact that coupling strength is related to the relative position of the antennas. As the application of double resonance sensing, tag-less human detection sensor is proposed. Here, the existance of human is detected using the antenna which has the resonance frequency corresponding to the human resonance frequency.
