Title: ACCELEROMETER
Abstract:
The invention related to an accelerometer including a cantilevered beam (1) with a free end, said beam comprising at least one piezoelectric layer (2) and at least one supporting layer (3), said free end of said beam being provided with an sensing mass (5) located excentrically in relation to the longitudinal direction of said beam. The accelerometer has a main direction of sensitivity (S) and a secondary direction of sensibility which is orthogonal to said main direction and in which the sensibility is negligible, said secondary direction forming an angle α relative to the longitudinal direction of said beam such that a line coinciding with a force, which is oriented through the gravitational center of said sensing mass and which is directed in said secondary direction of sensitivity, also intersects said beam.
