Information transmission through-human-body system and transmitter/receiver

Abstract

A signal is transmitted more stably by an information transmission through-human-body system. An electrode (104) of a transmitter / receiver (102) in contact with or capacitively coupled to a human body (101) is electrically connected through the human body (101) (mainly the chest portion or the left arm) to an electrode (108) of a receiver (106) in contact with or capacitively coupled to the human body (101). An electrode (105) of a transmitter / receiver (102) in contact with or capacitively coupled to the human body (101) is electrically connected to an electrode (109) of the receiver (106) so disposed as to face outward from the human body (101). The transmitter / receiver (102) and the receiver (106) communicate with each other through a path passing through the electrodes (104, 105, 108, 109) and the human body (101) and the capacitive coupling.

Description

technical field [0001] The present invention relates to an information transmission system and a transmitter-receiver through the human body for an information transmission through the human body. Background technique [0002] In recent years, communication using the human body as a transmission line has been eagerly proposed (for example, see Patent Documents 1-3). [0003] FIG. 6 is a system structural diagram of the information transmission system through the human body described in Patent Document 1. FIG. See, for example, US Patent Publication No. 5,914,701, column 1, line 60 to column 6, line 37; FIGS. 1 to 4 . In FIG. 6, a transmitter 402 is worn on one arm of a human body 401 and a receiver 405 is worn on the other arm. One electrode 403 of the transmitter 402 is in contact with or capacitance-connected with the human body 401 , while the other electrode 404 thereof is fixed while being directed to the outside of the human body 401 . In addition, one electrode 406...

Problems solved by technology

[0012] However, since the system of FIG. 8 is a system whose purpose is to be used as an ID card, it is constituted to be used with only one communication device worn on the human body, so it cannot be considered that its structure is that multiple communication devices are worn on the human body. on, and communicate between multiple communication devices
