Example Embodiment
[0084] figure 1 An electric hand-held device is shown in a cross-sectional view, the electric hand-held device including the detection device according to the present invention, wherein the hand-held device is gripped by a hand H. The transmitting electrode SE is arranged at the side wall of the electric hand-held device, and the receiving electrode EE is arranged at the side wall arranged opposite to this side wall. In this case, the transmitting electrode SE and the receiving electrode EE are arranged at the side walls of the handheld device opposite to each other, so that the two electrodes are at least partially covered by the hand during the gripping of the housing by the hand.
[0085] The transmitting electrode SE is coupled with a signal generator G, which generates a low-frequency alternating voltage. The emitter electrode SE is loaded with this alternating voltage. In performing this operation, the alternating electric field 20 is formed at the emitter electrode SE. T...
