Kurzbeschreibung (Abstract)
Vibration-based energy harvesting using piezoelectric circular diaphragms (PCDs) has drawn many attentions in the recent decades, in which a structure with the central mass (C-mass) configuration was widely employed. In this work, we propose a new configuration with the annular proof mass (A-mass) where an improved energy harvesting is promised. Combining the numerical analysis using the circuit-coupled piezoelectric simulation and experimental validation using the even-width annular the PCDs via modifying the mass configurations as well as the parameters piv1 and piv2 which indicates the ratio between the inner boundary radius and the piezoelectric ceramic radius and the ratio between outer boundary radius and the substrate radius, respectively. The impedance-matched output power of full-electrode PCDs was also collected with varying structural parameters and some distinct improvement was measured on certain structural parameters. The power increases from 14.1mW to 19.0mW after changing the configuration of samples from C-mass to A-mass with the same parameters (piv1, piv2)=(0.16,0.9), showing the considerable improvement in energy harvesting by using A-mass configuration.
