Designed High-Frequency Operation Piezo Elements for Cardiac Catheter Ablation Systems

The piezoelectric element resonance is used to generate energy for cardiac catheter ablation systems. The design of piezoelectric vibrators is closely related to the two major directions of material selection and geometry. In terms of standard AC to DC output power, its size is closely related to the external source form, the electromechanical properties of the vibrator (mass, damping, stiffness, force-electricity coupling, parasitic capacitance) and the external load connected to it.
