The fluidic drive for miniature acoustic-fluidic pump and mixer is comprised of 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. Acoustic streaming results due to the absorption of the acoustic energy in the fluid itself. This absorption results in a radiation pressure and acoustic streaming in the direction of propagation of the acoustic propagation or what is termed “quartz wind”.

The transmission cathode for X-ray generation is a device wherein an electrical current generated by a low voltage power supply produces an electron flow from the transmission cathode that is accelerated by a high voltage power supply towards an anode where X rays are emitted on impact. As the X rays are emitted, a primary beam passes through the cathode striking a sample placed outside the tube. The transmission cathode is X comprised of an electron emitter structure, preferably, an electron field emitter diode or thermionic emitter or a photoemitter or a nanotube or a pyroemitter or a piezoemitter, fabricated, preferably of elements of atomic numbers of 14 (silicon) or below, with electrically conductive components or conductive mechanical structural components, preferably, conductive silicon or diamond or aluminum or beryllium metal, and non-conductive electrical insulators or non-conductive mechanical structural components, preferably, diamond or silicon dioxide or boron carbide. The transmission cathode is transmissive to those X rays that freely flow through the transmission cathode.

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.
