摘要： A data input device includes a first electrode structure having a first collector electrode and a first plurality of finger electrodes extending from the first collector electrode and a second electrode structure including a second collector electrode and a second plurality of finger electrodes extending from the second collector electrode, the first and second electrode structures being arranged on a first carrier layer in such a way, that in an active area of the data input device, the first plurality of finger electrodes extend between the second plurality in an interdigitating arrangement. The device further including at least one shunting element arranged in the active area of the data input device on a second carrier layer in facing relationship to the interdigitating arrangement of the first and second plurality of finger electrodes such that, if the first and second carrier layers are pressed together in response to a force acting on the data input device, the at least one shunting element establishes an electrical contact between respective adjacent finger electrodes of the first and the second plurality of finger electrodes. According to the invention at least one of the first electrode structure, second electrode structure or shunting element including at least one series of resistive patches having different electrical resistances, the resistive patches of the at least one series being arranged along the active area in an order of increasing electrical resistance in such a way that the electrical resistance between respective terminals of the first electrode structure and the second electrode structure varies monotonically if an activation of the input device propagates monotonically along the series of resistive patches.
