Abstract
A sensing system includes an electronic tag and a reading device that transmits and receives information to and from the electronic tag. The reading device includes a transmission unit that sends an alternating-current radio wave including a high-frequency component and a low-frequency component. The electronic tag does not include a power supply and includes a receiving unit that obtains a power supply voltage from the high-frequency component of the alternating-current radio wave and obtains a clock signal from the low-frequency component and a return unit that maintains a maximum amplitude of the clock signal and sends a combination of information and the clock signal as a return signal. The reading device further includes a processing unit that decodes the return signal sent from the electronic tag on the basis of the clock signal.
