Synchronous circuits with self-adaptive mechanical switches of viscous material: A parameter study

Abstract

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.
