Dedicated units are generally needed for operating the switches in synchronous extraction circuits which are considered to be effective in enhancing the power of piezoelectric generators. This paper presents a novel design of self-adaptive mechanical switch using viscous materials. It can trace the displacement peaks and perform the switching operations synchronously with higher performance, less electronic components and lower voltage threshold. A parameter study shows that the relaxing time of the viscous material has different effects in the case of harmonic and noise excitations with varied optimization goals.
