In this case, since a reverse electric field is input from the ground electrode 301b of the transmitter 301 to the body of the user 300 as indicated by symbol b in this case, from the signal electrode 301a indicated by symbol a. The electric field of the user 300 is canceled by the reverse electric field indicated by the symbol b, and the electric field becomes small, and the electric field induced in the body of the user 300 is grounded through the user's 300 feet close to the ground 305 in particular. There is a problem that the electric field communication is difficult because the ground 305 escapes.

By setting the state, the electric field communication portable terminal 1 is operated while holding the transmission / reception electrode unit 11 extending downward in FIG.

  As described above, when the transmission / reception electrode unit 11 of the electric field communication portable terminal 1 is gripped by a user's hand, the transmission data from the computer 21 is in contact with the transmission / reception electrode 14 from the electric field communication transceiver 23 via the transmission / reception electrode 14. The electric field communication transceiver 23 receives the electric field that is induced and transmitted as an electric field to the user's hand, which is a transmission medium, and is transmitted to the hand and the like that is induced in other parts of the user via the transmission / reception electrode 14. By supplying the received data to the computer 21, the electric field communication portable terminal 1 performs electric field communication.

  The electric field communication transceiver 23 performs such electric field communication by an electro-optic technique using laser light and an electro-optic crystal. Specifically, as shown in FIG. 3, the data from the computer 21 is input, and the computer An input / output (I / O) circuit 101 for outputting data to 21 and data from the input / output circuit 101 are received and an electric field based on the data is transmitted via the transmission / reception electrode 14 and the insulating film 25 to transmit the data. A transmission circuit 103 that is induced in the living body 100 such as a user's hand, and an electric field detection optical that receives an electric field induced in another part of the living body via the insulating film 25 and the transmission / reception electrode 14 and outputs the data as electric signal data. Unit 105 and a signal that amplifies the electric signal data output from electric field detection optical unit 105 and processes and outputs a signal such as noise removal A sense circuit 107, and a waveform shaping circuit 109 supplies to the computer 53 via the input-output circuit 101 performs such wave-shaping the output signal of the signal processing circuit 107.

  The electric field detection optical unit 105 constituting the electric field communication transceiver 23 is induced and transmitted to the living body 100, and the electric field coupled through the insulating film 25 and the transmission / reception electrode 14 is electro-optic using a laser beam and an electro-optic crystal. 4 is a function of detecting an electrical signal, converting it into electrical signal data and outputting the electrical signal data to the signal processing circuit 107. Specifically, as shown in FIG. 4, an electro-optic element comprising a laser diode 221 and an electro-optic crystal 201. The electro-optic element 201 has sensitivity only to an electric field coupled in a direction perpendicular to the traveling direction of the laser light from the laser diode 221, for example, and the optical characteristics, that is, the birefringence changes due to the electric field strength. The polarization of the laser beam is changed by the change of the birefringence.

  First and second electrodes 203 and 205 are provided on both side surfaces of the electro-optic element 201 facing in the vertical direction in the figure, and the transmission / reception electrode 14 is connected to the first electrode 203, and the second electrode A ground electrode 207 is connected to 205. When the transmission / reception electrode 14 detects an electric field that is induced and transmitted to the living body 100, the transmission / reception electrode 14 transmits the electric field to the first electrode 203 and is coupled to the electro-optic element 201 through the first electrode 203. ing.

  The laser light output from the laser diode 221 is converted into parallel light via the collimator lens 223, and the laser light that has become parallel light is adjusted in polarization state by the first wave plate 211 and enters the electro-optical element 201. . The laser light incident on the electro-optic element 201 propagates between the first and second electrodes 203 and 205 in the electro-optic element 201. During the propagation of the laser light, the transmission / reception electrode 14 is induced in the human body. When the transmitted electric field is detected and this electric field is coupled to the electro-optic element 201 via the first electrode 203, the electric field is connected to the ground electrode 207 from the first electrode 203. The birefringence, which is the optical characteristic of the electro-optic element 201, changes, and thus the polarization of the laser light is changed, because it is perpendicular to the traveling direction of the laser light incident on the electro-optic element 201 from the laser diode 221. Changes.

  In this way, the laser light whose polarization has been changed by the electric field from the first electrode 203 in the electro-optical element 201 is adjusted in polarization state by the second wave plate 213 and enters the polarization beam splitter 215. The polarization beam splitter 215 separates the laser light incident from the second wave plate 213 into P wave and S wave, and converts them into a change in light intensity. The laser beams separated into the P-wave component and the S-wave component by the polarization beam splitter 215 are condensed by the first and second condenser lenses 225 and 231 respectively, and then the first and second photodiodes 227 are collected. 233, the first and second photodiodes 227 and 233 convert the P-wave optical signal and the S-wave optical signal into respective electric signals and output them.

  The electric signals output from the first and second photodiodes 227 and 233 are subjected to signal processing such as amplification and noise removal by the signal processing circuit 107 of the electric field communication transceiver 23, and waveform shaping by the waveform shaping circuit 109. To the computer 21 via the input / output circuit 101.
