| 摘要 |
The present invention relates to a temeperature-compensated piezoelectric acceleration, force or pressure sensor comprising, on each side of a plate (1), a piezoelectric element (2, 3) and a moving mass (4, 5), the piezoelectric elements and the moving masses being identical; means (6) for rigidly joining the two moving masses by compressing the piezoelectric elements; the first electrode (11) integral with the faces of the piezoelectric elements which are turned towards the plate; and a second electrode (12) integral with the faces of the piezoelectric elements which are turned towards the moving masses. The piezoelectric elements are sheets of a piezoelectric polymer, the two sheets being polarised in the same direction and the same sense, orthogonally to the plane of the plate. <IMAGE>
