High frequency transducer for vessel imaging based on lead-free Mn-doped (K0.44Na0.56)NbO3 single crystal

We report a high frequency ultrasonic transducer up to 50 MHz for vessel imaging based on a lead-free (K0.44Na0.56)NbO3–0.5 mol. % Mn (Mn-KNN) single crystal, which has a high electromechanical coupling coefficient k t of 0.64 and a large thickness frequency constant N t of 3210 kHz · mm. The Krimho...
