COMPONENT FOR ELECTRICALLY CONTACTING A PIEZO STACK, A PIEZO STACK, AND METHOD FOR PRODUCING THE SAME

摘要

A piezo component with a contacting component for electrically contacting a piezo stack. The contacting component has an electrically conductive meandering structure for bringing the contacting component into electric contact with inner electrodes of the piezo stack and an electrically conductive contacting device for electrically contacting the contacting component from outside the piezo stack. The meandering structure and the contacting device are arranged at a distance from each other, and a connection element is provided in order to connect the contacting device and the meandering structure in an electrically conductive manner and simultaneously decouple forces between the contacting device and the meandering structure.
