Abstract
An ultrasonic device for transversely manipulating drug delivery carriers includes a driving unit and a transducer. The transducer is electrically connected to the driving unit and has a piezoelectric sheet in a curved shape. The piezoelectric sheet includes a plurality of channels, and a phase difference is generated between every two of the channels by the driving unit for producing an acoustic vortex.
