ABSTRACT:
A pill inserted into a body of a patient acquires in-vivo information on the body of the patient. The in-vivo information on the body of the patient is input to a receiver from the pill through a receiving antenna. The pill receives a power-supply signal from the receiver through a power receiving antenna, and a power recovering circuit recovers power from the power-supply signal. A level determining circuit compares the power recovered with a predetermined value to determine the strength of the power-supply signal, and wirelessly transmits the determination result signal to the receiver.
