Abstract
An ingestible sensor according to an embodiment includes a sensor, a detector, and a transmitter and to be mixed with food and discharged without being digested or absorbed also when entering the inside of a body. The sensor is configured to detect a predetermined substance disposed inside the body. The detector is configured to detect whether or not the sensor has entered the inside of the body. The transmitter is configured to transmit information of the predetermined substance detected by the sensor to a communication device disposed outside the body based on a detection of an entrance of the sensor into the inside of the body that is made by the detector.

1-11. (canceled)
A swallowable sensor to be discharged without being digested or absorbed also when entering inside of a body, the swallowable sensor comprising:
- a sensor configured to detect predetermined biological information on the inside of the body;
- a detector configured to detect whether the sensor has entered the inside of the body;
- and
- a transmitter configured to transmit the predetermined biological information detected by the sensor to a communication device disposed outside the body based on a detection of an entrance of the sensor into the inside of the body that is made by the detector,
- wherein the sensor, when detected by the detector as being entered inside the body, starts sensing the predetermined biological information on the inside of the body and detects the predetermined biological information on the inside of the body by decreasing frequency of the sensing in accordance with a time elapsed after entering the body.
A sensing method performed by a swallowable sensor including a sensor configured to detect predetermined biological information on inside of a body, a detector configured to detect whether the sensor has entered the inside of the body, and a transmitter configured to transmit the predetermined biological information detected by the sensor, the method comprising:
- detecting, using the detector, whether the sensor detecting the predetermined biological information on the inside of the body has entered the inside of the body;
- starting sensing, using the sensor, the predetermined biological information on the inside of the body based upon detection of the sensor entering inside the body and detecting the predetermined biological information on the inside of the body by decreasing frequency of the sensing in accordance with a time elapsed after the sensor entering the body;
- and
- transmitting, to a communication device disposed outside the body, the predetermined biological information detected by the sensor at the detecting.
