In this paper an equivalent circuit model is established for an ultrasonic micro-knife, which is fabricated by using MEMS Technology and driven by the piezoelectric PZT-4 plates. In this model, the overall electrical characteristics of micro-knife is equivalent to a RC network, the mechanical properties reflected in a form of series resonance branch, and… CONTINUE READING
