Description

The present invention relates to a communication system including a first communication device and a second communication device that communicates between the first communication device.

Conventionally, in a communication system using short-range radio performed in an area near the human body, there is a possibility that communication is performed to an unspecified number of people without noticing it due to an erroneous activation. If a mechanical button is mounted, it takes time and effort for the user to turn the power on and off, which is disadvantageous in terms of size and cost.

Furthermore, when a security system is introduced, it is important to save power when not in use, but it is difficult to control the power on / off diligently. Further, a system in which a power source is activated by a human operation using an acceleration sensor or a proximity sensor, which are widely used, can be easily realized, but a erroneous activation is likely to occur, and there is a problem in power saving.

Patent Document 1 discloses a communication device having a human body as a transmission line. It seems that communication cannot be performed when there is no person between the communication devices. In the present invention, in addition to using the human body as a transmission line, it is intended to suppress deterioration of antenna performance by performing wireless communication with an antenna. It seems that communication cannot be performed when there is no person between the communication devices.

Patent Document 2 discloses that the state of biocommunication is acquired from the vicinity of a portion that the user's human body touches for biocommunication. Specifically, when a person touches it, it conveys that data communication is being performed by vibration or heat.

Further, Non-Patent Document 1 discloses that various forms of systems are possible by using the human body as a transmission line. It is disclosed that this method of communication measures biometric information with a measuring instrument and sends the biometric information to a terminal held by the patient.
