Abstract

The disclosure relates to the technical field of capacitive touch panels and discloses a touchpen which may be used in mobile phones, computers and other devices with touch panels for writing characters, letters and other symbols. In particular it relates to a capacitive touchpenfor inputting information into an electronic devicethrough touching of a capacitive touch panel, the capacitive pen comprising an elongated body membercomprising a conductive partand a tipdisposed at one end of the body memberhaving a contact surfacefor contacting the capacitive touch panel. The conductive partis configured such that the distortion of the touch panel's electrostatic field caused by the conductive partwhen changing the position of the touchpenin relation to the capacitive touch panel, when the contact surface is kept in contact with the touch panel, is sufficient to register a change in capacitance by the capacitive touch panel. The disclosure further relates to methods for detecting the position of a touch pen as well as to an electronic device and a computer program.
