Description

  The present invention relates to a human body communication electrode, and more particularly to a human body communication electrode suitable for being arranged at an arbitrary place.

  Human body communication is configured such that communication is established based on an electrical relationship by means of capacitive coupling between a stationary device, a mobile device, and each of the human bodies located between the stationary device and the mobile device. The fixator is arranged on the facility side such as the floor, and the mobile device is equipped on the human body. The fixing device and the moving device are composed of a control unit and electrodes. As capacitive coupling, there are a capacity between the human body and the mobile device, a capacity between the human body and the fixed device, a capacity between the mobile device and the floor, and a capacity between the fixed device and the floor.

  As a normal electrode of a fixing device in human body communication, as shown in FIG. 8, for example, an electrode plate 100 including a + electrode plate 101 located on the upper side and a − electrode plate 102 located on the lower side is used. . The planar shape of the electrode plate 100 is usually a rectangle such as a square. The electrode plate 100 has a flat plate shape having a required thickness, and is usually installed on a flat floor 103 (or the ground or the like). In FIG. 8, reference numeral 104 denotes a human body communication device as a mobile device mounted on the human body 105. Further, in FIG. 8, a plurality of arrows 106 represent electric lines of force. Communication is possible via the electric lines of force 106 between the electrode plate 100 and the human body communication device 104. Between the + electrode plate 101 and the − electrode plate 102, between the + electrode plate 101 and the human body 105, between the floor 103 and the − electrode plate 102, between the human body 105 and the floor 103, and between the + electrode plate 101 and the − electrode plate 102. In between, electric field lines 106 are generated, respectively.

  According to the conventional human body communication device, as described above, the electrode plate 100 as the stator side electrode is necessary. Both the + electrode plate 101 and the − electrode plate 102 constituting the electrode plate 100 are generally formed of a metal plate that is a conductor. Therefore, the electrode plate 100 is usually rigid and does not have deformability or flexibility.

  Patent document 1 is given as an example of prior art documents. Patent document 1 is disclosing the electrode for electric field communication apparatuses. According to the electrode for the electric field communication device, one linear electrode is bent and formed in various patterns on the surface of the electrode arrangement member so as to generate a required gap (FIGS. 1 to 6). etc). With this configuration, a gap is generated in the electrode arrangement region on the surface of the electrode arrangement member, and the capacitive coupling between adjacent electrodes is weakened. Further, by forming an electrode by bending a single continuous wiring, simple and inexpensive manufacturing is possible.

  DESCRIPTION OF EMBODIMENTS Preferred embodiments (examples) of the present invention will be described below with reference to the accompanying drawings.

  The principle and configuration of human body communication in which the human body communication electrode according to the embodiment of the present invention is used are the same as those described with reference to FIG. FIG. 1 shows a basic configuration on the fixing device side installed on the facility side. In FIG. 1, 10 indicates an electrode, 10A indicates a positive electrode element, and 10B indicates a negative electrode element. In FIG. 1, the electrode 10, the + electrode element 10 </ b> A, and the − electrode element 10 </ b> B are shown as blocks and are shown conceptually. In the conventional electrode, the + electrode element 10A and the -electrode element 10B are each formed of a rectangular metal plate, and are usually arranged one above the other via an insulating medium. The + electrode element 10A and the − electrode element 10B can be arranged side by side in the horizontal direction on the same plane, or can be arranged side by side in the horizontal direction and partially overlapping each other. . In the present embodiment, the + electrode element 10A and the − electrode element 10B that form the electrode 10 are configured using deformable linear conductive members (wires or the like) as described below.

  Each of the positive electrode element 10A and the negative electrode element 10B of the electrode 10 is connected to each terminal of the control unit 12 via a cable 11 portion. In the space region around the + electrode element 10A and the -electrode element 10B of the electrode 10, electric lines of force (electric lines of force 106 described in FIG. 8) are generated between the required locations, and the electric lines of force are passed through. The signal detected in this way is taken into the control unit 12 to enable human body communication.

  FIG. 2 shows a first embodiment of a human body communication electrode according to the present invention as a specific configuration of the + electrode element 10A and the −electrode element 10B that form the electrode 10 described above. This human body communication electrode is an electrode on the fixing device side, and is formed by bending one wire 21A and 21B into a predetermined pattern shape having the same shape. In the example shown in FIG. 2, each of the two wire rods 21 </ b> A and 21 </ b> B is formed as a spiral pattern 21 </ b> A- 1, 21 </ b> B- 1 by bending its tip portion into, for example, a rectangular spiral state. Each of the spiral patterns 21A-1 and 21B-1 of the two wires 21A and 21B has a form wound so as to be included in the same plane or curved space, and the spiral pattern 21A- of the wires 21A and 21B. 1 and 21B-1 form the above-mentioned + electrode element 10A and-electrode element 10B, respectively. Since the spiral pattern 21A-1 and the spiral pattern 21B-1 are formed as a spiral pattern having the same shape, they coincide with each other when they are vertically stacked. The size of the spiral pattern and the distance between the gaps are arbitrary.

  The wire rods 21A and 21B are linear conductive members (conductive wires, wires, metal cords, deformable metal materials, metal pipe materials, etc.), and their lengths and diameters can be arbitrarily set. Any material can be used as long as it generates electric lines of force. The wire rods 21A and 21B have deformability or flexibility that can freely change their shapes. Therefore, when the human body communication device is installed at a required installation location, the operator carries the wire rods 21A and 21B that originally have one linear shape to the installation site of the fixing device, and the site environment and installation at the installation site. It becomes possible to bend and install according to the shape of the place. The spiral patterns 21A-1 and 21B-1 of the wire rods 21A and 21B are examples of modifications.

  In the above-described linear conductive member, the conductive wire may remain bare or may be covered with an insulating coating member.

  In the human body communication electrode according to the present embodiment, the + electrode element 10A and the − electrode element 10B forming the electrode 10 are formed of only the wire materials 21A and 21B having the spiral patterns 21A-1 and 21B-1, and the wire materials 21A, 21A, A substrate on which 21B is placed or supported is not used.

  The shape of the electrode pattern formed on the wires 21A and 21B can be modified as shown in FIG. In FIG. 3, for example, only the shape of the electrode pattern on one side on the + side is shown.

  FIG. 3A shows the same spiral pattern 31 as the spiral patterns 21A and 21B described in FIG. In the spiral pattern 31, the connection point 31a with the control unit 12 is provided at the position of the outer end.

  FIG. 3B shows another spiral pattern 32. In the spiral pattern 32, the connection point 32a is provided at the position of the inner end.

  FIG. 3C shows a zigzag or bellows pattern 33. In the pattern 33, the length of the folded portion and the interval between the folded portions can be arbitrarily set. One end of the pattern 33 is a connection point 33a.

  FIG. 3D shows a saddle-shaped pattern 34. The intersection of the central part of the pattern 34 is a connection point 34a.

  FIG. 3E shows a pattern 35 having a short-circuit loop shape (ring shape or ring shape). A connection point 35 a is provided at an arbitrary position of the pattern 35.

The electrode pattern is not limited to the above-described circle or rectangle, and may be a polygon, a regular shape, or an irregular shape.
Further, the loop-shaped pattern 35 may have a shape in which a part is opened.
In the above embodiment, the + side electrode element and the − side electrode element have been described as having the same shape. However, the + side electrode element and the − side electrode element can be manufactured to have different lengths and shapes.
Moreover, the end of the wire forming the electrode pattern may be open or short-circuited.

  FIG. 4 shows an example in which the human body communication electrode according to the first embodiment is arranged in the security gate. In FIG. 4, reference numeral 41 denotes a gate, and reference numeral 42 denotes a person who wants to pass through a passage set by the gate 41. The person 42 equips the body with a mobile device (human body communication device) 43. In the illustrated example, an obstacle 45 exists on the floor surface 44. On the surface or inside of the floor surface 44, the wire rods 21 </ b> A and 21 </ b> B are installed as a substantially scribble electrode pattern 33 while avoiding the obstacle 45. Since the zigzag electrode pattern 33 is made avoiding the obstacle 45, the pattern 33 shown in FIG. 3C is deformed. One end of each of the wire rods 21 </ b> A and 21 </ b> B is connected to the control unit 12. Reference numeral 46 denotes electric lines of force. Thus, according to the electrode for human body communication concerning this embodiment, it can be freely installed in the installation site according to the environment and shape of the place where the electrode is installed.
