A pressure sensor including a lower substrate having two electrodes partially covered with a semiconductor layer and a piezoelectric layer made of a piezoelectric material, and in contact with the semiconductor layer in such a way that semiconductor material is in contact with the piezoelectric material and with the two electrodes, deposited thereon. The electrodes are intended to be connected to a voltage source or to a device for measuring the intensity of a current generated by the displacement of the electric charges in the semiconductor layer between the electrodes, said electric charges being created when a pressure is exerted on the piezoelectric layer. |
