Abstract
A piezoelectric generator includes a piezoelectric element, a spring element, a mass element, and at least one stop. The piezoelectric element, the spring element, and the mass element form a system which can oscillate. The stop limits the oscillation of the system which can oscillate, at least on one side. The stop is formed from a ductile material or has a coating of a ductile material.
