Vibrations are a problem, which are encountered at almost every technical application when there are moving parts or fluids included. Upon the need for lightweight structures, especially in aerospace applications or electric mobility, conventional damping concepts are insufficient because of their extra-weight and low performance at low frequencies. Measures for active noise and vibration re-duction have the potential to solve these drawbacks of passive systems.. How-ever, a limitation of these concepts arises from the need for complex system mod-els for deriving the controllers. This leads to another possibility to reduce vibrations consisting of piezoelectric transducers attached to the structure and connected to hybrid electric networks. Within this paper, the basic principles of shunt damping, two hybrid electric networks circuits and the experimental validation of a damped system will be shown. Finally - as a challenging example - a circular saw blade is equipped with piezoelectric transducers and negative capacitance hybrid electric networks to reduce the vibration and noise amplitude excited by the cutting process.
