| 摘要 |
A printed circuit board for generating and supplying an electronic unit with autonomous energy comprises a plate-like carrier (4) of constant thickness and a bending transducer (2) comprising the carrier (4) and at least one piezoelectric layer (16a, b) applied thereto, wherein, in the bending transducer (2), the carrier (4) comprises a forward bending region (14) and extends in the longitudinal direction (10) from a fastening region (6) to a deflecting end (8), wherein the piezoelectric layer (16a, b) is applied in the forward bending region (14) and wherein, adjoining the fastening region (6), the carrier (4) comprises a narrowing region in which a width of the carrier (4) reduces in the direction of the deflecting end (8). |
