ultrasonic atomizer

[¦əl·trə′sän·ik ′ad·ə‚mīz·ər]
(mechanical engineering)
An atomizer in which liquid is fed to, or caused to flow over, a surface which vibrates at an ultrasonic frequency; uniform drops may be produced at low feed rates.

For the ease of handling high molecular weight polymers for the given capacity of ultrasonic atomizer, the concentrations of solutions were kept as low as 1 wt%.
Compared with the atomization through pressurized nozzles, ultrasonic atomizers offer smaller drop sizes with more uniform size distribution.
(The obfuscation of language and evanescence of breath are recurring themes, reflecting the artist's fascination with both the capabilities and limits, and the uses and abuses, of media technologies.) In forgoing completeness, the survey is also able to foreground the unusual material and phenomenological diversity of Lozano-Hemmer's works, in forms ranging from 3-D-printed aluminum sculptures to mists of water shaped by ultrasonic atomizers and gold nanopamphlets inhaled from the air.
Some of the works premiere at "Decision Forest." Visitors can have their portrait made of water vapor as a face recognition system captures their faces and recreates it with ultrasonic atomizers in "Pareidolium." A few drops of Sulwhasoo fragrance is added to the water used for this piece to match with the parent company's cosmetic business.
The hydraulic atomizer uses only a water supply, while pneumatic and ultrasonic atomizers required both water and compressed air.
