| Abstract: | A piezoelectric power-generation device and the corresponding circuit for energy transformation and storage were designed and fabricated through the study on the mechano-electric energy transformation of the piezoelectric ceramics and their electricity storage characteristic.Based on this,a novel wireless electropult using the piezoelectric self-powersupply was developed and its tests were performed.The developed wireless electropult is characterized by the strucutre simplicity,miniaturization and integration,easy to fabricate,without thermal load,environment pollution and electromagnetic interference.It provides a new option for the power supply in a variety of portable miniature electronic facilities,passive sensors,and monitoring systems. |
