Abstract
A vibration sensor based on piezoelectric thin films, or smart cuts of piezoelectric materials, integrated into a functional, metallic housing that transmits vibration deformations applied to the housing correctly into the sensor in a frequency range that is typically—but not limited to—1 Hz to 20 kHz. The sensor comprises a low-stiffness layer, for instance a PCB layer, providing a controllable contact force between sensor structure machine parts, and transforming the relative movements into a mechanical stress acting onto the piezoelectric layer.
