Abstract:
1. A device for an electric hand-held device for detecting a clasping of the hand-held device by a hand, comprising: at least one transmitting electrode configured to emit an alternating electric field, and at least one receiving electrode arranged to receive the alternating electric field is at least partially, an electrically conductive structure connected with a ground potential of the electric hand-held device; wherein the at least one transmitting electrode and the at least one receiving electrode are arranged at the hand-held device such that each is at least partially covered by the hand when the hand-held device is being clasped with the hand, wherein when the hand-held device is being clasped with the hand a first portion of the alternating electric field emitted by the transmitting electrode is coupled into the receiving electrode via the hand, wherein the first portion of the alternating electric field is a characteristic representative of a clasping of the hand-held device by the hand, and wherein the electrically conductive structure is arranged with respect to the at least one transmitting electrode such that when the electric hand-held device is not clasped by the hand, the alternating electric field is prevented from coupling into the at least one receiving electrode.
