摘要
The sensor has structured resistance tracks (4) applied directly or via a carrier material (3) to a spring material. In addition, a layer (2) of piezoelectric strain-sensitive material is applied to the carrier layer or to the spring material, and electrodes (7,17) are spaced apart at points in the strain direction. The voltage across the electrodes is proportional to a change in the strain.
