Embodiment Construction

[0042] Although the invention allows many different forms of embodiments, one or more specific embodiments are shown in the drawings and will be described in detail herein, in which it is understood that the present disclosure is to be regarded as an example of the principles of the invention and does not It is intended to limit the invention to the specific embodiments shown and described.

[0043] figure 1 A schematic electrode arrangement of the BCC system as discussed above is shown. The plates can be oriented parallel to each other and parallel to the skin of the body in which the plates are applied; this arrangement is shown in the figure. This arrangement is not necessary; the plates can also be arranged parallel to the skin but side by side, with the two plates in the immediate vicinity of the skin. To point out that in figure 1 One of the plates is marked as "GND" for ground. Although this is an option, it is not necessary.

[0044] In BCC, the signal is transmitted via...

Abstract

Body coupled communication device (200; 201) arranged to receive signals via a body transmission channel (260), the device (200) comprising - two couplers (202, 204) arranged to receive a body-coupled signal from the body transmission channel (260), the body transmission channel (260) being formed by a body of a user (150) when the body is in the direct vicinity of the couplers (202, 204), - a receiver amplifier (206) coupled to at least one of the two couplers, - an inductance (220) for matching the impedance of the receiver amplifier, the inductance being arranged in parallel to the couplers.

Description

Technical field [0001] The invention relates to a body-coupled communication device arranged to receive signals via a body transmission channel. Background technique [0002] Body-coupled communication (BCC) or body-based communication has been proposed as a promising alternative to radio frequency (RF) communication, for example as a basis for body area networks (BAN); an example is the Institute of Electrical and Electronics Engineers (IEEE ) The standard of the 802.15.6 task group. BCC allows information to be exchanged between multiple devices at or very close to the human or animal body. This can be achieved by capacitive or galvanic coupling of low-energy electric fields to the surface of the body. [0003] In a capacitive body coupled communication (BCC) system, information is transmitted from a transmitting device to a receiver device via a capacitive coupling signal on the user's body. Body-coupled communication uses electric fields instead of electromagnetic fields to ...
