BNBTM and SCNN lead-free ultrasonic transducer for underwater propulsion system

BNBTM and SCNN transducer are investigated as the lead-free acoustic propulsion system. Propulsion measurements are studied to evaluate the performance of BNBTM, SCNN and PZT transducers. The propulsion of the BNBTM and SCNN transducers were 6mN and 0.7mN, when the input power was 3.5W. BNBTM is expected to be a suitable material for endovascular treatment, because of harmless and good performance.
