Abstract
This paper compares the performances of
vibration-powered electrical generators using a piezoelectric ceramic and a
piezoelectric single crystal associated to several power conditioning
interfaces. A new approach of the piezoelectric power conversion based on a
non linear voltage processing is presented, leading to three novel
high-performance techniques. Theoretical predictions and experimental
results show that the novel techniques may increase the power harvested
above 800% compared to standard techniques.
