Abstract :
Using two pieces of piezoelectric ceramics, a two-stage energy harvester for an application of micro Ultrasonic Electrical Discharge Machining (UEDM) is developed in this article. Ceramics in the first stage (PZT#1) plays the role of actuator driven with oscillation of high frequency and amplitude. In the second stage (PZT#2), the ceramics receives part of the power transmitted from the actuator in the first stage and generates electricity of satisfactory voltage and current for the application requirement. Modeling of the practical system with implementation of springs in between and outside of the ceramics and the weight ratio of the two ceramics in order to enhance durability in operation and gain better performance is investigated.
