Patent ID: 7064747

Claim:
A touch-sensitive detection element, comprising: a detection surface; a conducting element; a first set of electrodes including at least one electrode extending parallel to the detection surface, each electrode electrically isolated, the first set of electrodes forming a first interaction capacitor with the conducting element; a second set of electrodes including at least one electrode extending parallel to the detection surface, each electrode electrically isolated, the second set of electrodes forming a second interaction capacitor with the conducting element, the second interaction capacitor having a lower capacitance than the first interaction capacitor; a first set of detectors arranged for detecting a signal emitted by at least one electrode of the first set of electrodes and transmitted through an external element contacting the detection surface at the electrode emitting the signal and at a detector of the first set of detectors; and a second set of detectors arranged for detecting a signal emitted by at least one electrode of the second set of electrodes and transmitted through an external element contacting the detection surface at the electrode emitting the signal and at a detector of the second set of detectors.
