Abstract
A sensor arrangement for an electronic device with user input means comprises a sensor. The sensor is adapted to generate an electric field in an area of the user input means and to enable a detection of a change in the electric field. The sensor arrangement further comprises a conductive web. The conductive web is arranged between the sensor and an external surface of the user input means, in order to concentrate the volume of the generated electrical field.
