The invention relates to an input device 1 for capacitive touch-sensitive displays, wherein the device is a simple pen 11, wherein the simple pen can be sharpened, wherein the device is present as a core, or wherein the device is present as a core with a coating, or wherein the device is present as a core with a casing, or wherein the device comprises a core, a casing and a coating, wherein the core, the casing and/or the coating are configured to be electrically conductive, wherein an element, a contacting element 12 for a tablet/display is formed at one end of the device, and wherein the contacting element is formed as an electrically conductive material.

An input device for an electronic device includes a circuit unit including a reactance element with a variable reactance, and a recording member configured to record on an intermediate medium and coupled with the reactance element. As a recording on the intermediate medium proceeds, writing pressure is transferred to the recording member so that the reactance of the reactance member may vary.
