1. A capsule-type endoscope capable of two-way communication, comprising:
an RFID receiving antenna receiving an RFID signal;
a first matching circuit for impedance matching with the RFID receiving antenna;
a human body communication electrode comprised of a ground electrode and a signal electrode transmitting a signal for human body communication;
a second matching circuit for impedance matching with the human body communication electrode;
a first switch for opening and closing a connection between the RFID receiving antenna and the first matching circuit; and
a second switch opening and closing a connection between the signal electrode of the human body communication electrode and the second matching circuit;
wherein the first switch connects the RFID receiving antenna and the first matching circuit when the RFID signal is received, and opens a connection between the signal electrode of the human body communication electrodes and the second matching circuit when the human body communication signal is transmitted, and
the second switch connects the signal electrode of the human body communication electrode and the second matching circuit when the human body communication signal is transmitted, and opens a connection between the RFID receiving antenna and the first matching circuit when the RFID signal is received.
