Summary:We have developed an efficient atomization method using modification of a silver electrode on an ultrasonic transducer. A circular silver electrode, which is conventionally used as a standard electrode on a transducer, is chemically replaced with a rectangular silver electrode. The rectangular electrode inherently creates a flattened conical water column, generating laterally directional wobbling perpendicular to the long axis of the rectangular electrode. This directional wobbling generates intense centrifugal force, stretching the water column and reducing the pressure in the column, thus causing more cavitation for effective atomization, achieving 2.93 times more efficient atomization than a standard circular electrode. This method will greatly contribute to the fields of engineering, medicine, and biology where various types of solutions are highly expected to be atomized more efficiently.
