Apparatus and method for capacitive data transmission

Server device, comprising a server circuit (S) with a first server electrode (S1), wherein the first server electrode (S1) with a first client electrode (C1) at least one client device is capacitively coupled, wherein the server circuit comprises (S) means for generating an alternating electric field (fc) attached to the first server electrode (S1) can be emitted and the first client electrode (C1) can be coupled, so that between server device and client device, a circuit (I) forms, whereby to change a client circuit (C) is at least designed in a client device, an impedance in the circuit (I), which causes a change in load for the server circuit (S), and wherein the server circuit comprises (S) means (D, D2) for detecting the induced by the at least one client circuit (C) change in load in the server circuit (S), characterized, in that the server circuit (S) a second server electrode (S2), wherein the second server electrode (S2) with a second client electrode (C2) ...
