    Abstract: Articles of manufacture, including an apparatus for acoustic wave based atomization, are provided. The apparatus may include a monocrystalline piezoelectric substrate. The monocrystalline piezoelectric substrate may include a surface patterned with at least one wetting region. The monocrystalline piezoelectric substrate may be configured to respond to an electric signal by at least generating acoustic waves including, for example, surface acoustic waves, Bluestein-Gulayev waves, Lamb waves, Love waves, flexural waves, thickness mode vibrations, mixed-mode waves, longitudinal waves, shear mode vibrations, and/or bulk wave vibrations. The acoustic waves may atomizing at least a portion of a material collected within the at least one wetting region to form a mist of the material. Methods for acoustic wave based atomization are also provided.

    Abstract: An ultrasonic generator is provided. The ultrasonic generator includes an amplifier for outputting a drive signal to an ultrasonic atomizing nozzle, and a microcontroller, coupled to the amplifier, to control an output power of the amplifier. The microcontroller includes a load leveling operating mode in which the output power of the amplifier fluctuates to match changing load conditions of the ultrasonic atomizing nozzle.

    Abstract: In an ultrasonic frequency generating assembly including a frequency generator coupled to a transducer through an output stage, a current measuring circuit is coupled to the output stage for sampling the current therethrough during each frequency burst upon the passage of a predetermined time interval following the onset of the respective frequency burst. The current value measured during a frequency burst is compared with a measured current value from an immediately preceding burst, the frequency output of the frequency generator being modified in accordance with the results of the comparison. The compared current values are stored in respective memories, the most recently measured current value being transferred from one memory to the other upon the termination of the comparison. A new current value is then loaded into the first memory.

    Abstract: A drive circuit for an ultrasonic atomizer comprising a switching mode power driver circuit and an oscillator circuit to drive the power driver circuit with a signal proportional to the phase response of the atomizer's transducer element so as to fix the frequency of the power delivered to the atomizer at the frequency of the transducer. The oscillator circuit has an oscillator which generates and supplies said drive signal, an integrated circuit phase-locked loop in a feedback loop arrangement to detect the transducer's phase response and signal the oscillator to shift its drive signal frequency to the transducer's frequency and a second order low pass filter to control the rate of the oscillator frequency shift.
