A method for fabricating a transducer suitable for a fluidic drive for a miniature acoustic-fluidic pump or mixer that includes an acoustic transducer attached to an exterior or interior of a fluidic circuit or reservoir. The transducer converts radio frequency electrical energy into an ultrasonic acoustic wave in a fluid that in turn generates directed fluid motion through the effect of acoustic streaming. The method includes depositing a piezo-electric thin-film onto a platinum coated silicon wafer or substrate with capping electrodes, defining each separate transducer; and dicing said piezoelectric tin-film to provide individual transducers.
