Title: INDUCTIVE TOUCH SENSOR AND METHOD FOR OPERATING SAME
Abstract:
The invention relates to an inductive touch sensor (10), having: at least one magnetic field generating element (12a, 12b) for generating a magnetic field; at least one resonance element (14a, 14b), which is arranged in the magnetic field of the magnetic field generating element (12a, 12b); a positioning element (16) for positioning the at least one resonance element (14a, 14b) relative to the at least one magnetic field generating element (12a, 12b), wherein the position of the resonance element (14a, 14b) can be varied relative to the at least one magnetic field generating element (12a, 12b) so that the resonance generated by the magnetic field in the resonance element (14a, 14b) consequently changes; and an evaluation circuit for evaluating the change in the resonance of the resonance element (14a, 14b), so that an operation of the inductive touch sensor is consequently detected.
