ABSTRACT:
A touch-sensitive detector includes a detection surface and a conducting element, and a first and second set of electrodes, each set of electrodes including at least one electrode extending parallel to the detection surface and where each electrode is electrically isolated. A first and second interaction capacitor is formed by the conducting element with the first and second set of electrodes, respectively. The second interaction capacitor has a lower capacitance than the first interaction capacitor. The touch-sensitive detection element further includes a first and second set of detectors arranged for detecting a signal emitted by at least one electrode of the first set of electrodes and the second set of electrodes, respectively, and transmitted through an external element located at the electrode emitting the signal. The external element contacts the detection surface. A touch sensitive detection method is also provided.
