Abstract
The inertial sensor comprises a piezoelectric plate having a vibrator member defined therein that carries excitation electrodes connected to an excitation circuit comprising conductor tracks carried by the piezoelectric plate, the excitation circuit including a disturbing circuit portion in which two conductor tracks extend on either side of a midplane and present a width less than 50 μm, and preferably equal to 10 μm, and are spaced apart by a distance of less than 100 μm, and preferably equal to 40 μm.
