Abstract
A functionalized object includes at least one mechanical wave sensor providing the object with a vibration and deformation detection capability. The mechanical wave sensor comprises: a sensitive cell having a thickness less than or equal to 50 microns, and comprising an active layer made of a monocrystalline or polycrystalline piezoelectric material and two electrodes, which are in contact with the active layer and accessible at a first surface of the sensitive cell, and a support layer secured to the second surface of the sensitive cell and secured to the object. The functionalized object comprises at least two electrically conductive strips disposed on the first surface of the sensitive cell and on a surface of the object, each strip connecting an electrode to an electrical contact pad. A method is used for producing such a functionalized object.
