Abstract
A piezoelectric transducer including a polarized piezoelectric material film, which also has a reinforcing material incorporated into the mass and which prevents any deformation of the film in certain given directions. The invention also relates to a pressure sensor using such a transducer. This sensor can be used both as a pressure sensor and as a pressure gradient measuring device.
