We propose a system to transmit and store electric energy by using transmitting element, a chargeable battery, and a rectifier together with a dc-dc converter to connect the two components as an integrated system. The transmitting element is modeled by two piezoelectric transducers. One is as the driving transducer for generating acoustic wave; the other is as the receiving transducer for converting the acoustic energy into electric energy. A dc-dc converter employed in the storage circuit is to match the optimal output voltage of the receiving transducer with the battery voltage for efficient charging. A synchronized switch harvesting on inductor (SSHI) in parallel with the receiving transducer is introduced to artificially extend the closed circuit interval of the rectifier. This analysis extends a previous one by considering that influence of wall thickness which always exists in the application. The characteristics of the energy-transmitting element are studied. Performance of the energy-transmitting element is optimized by synthetic adjusting parameters of the element, and carefully choosing input frequency of electric source.
