ULTRASONIC APPLICATORS WITH UV LIGHT SOURCES AND METHODS OF USE THEREOF

Abstract:

A material applicator includes an array plate and at least one ultrasonic transducer mechanically coupled to the array plate. The array plate includes a plurality of micro-applicators and each of the micro-applicators has a material inlet, a reservoir, and a micro-applicator plate in mechanical communication with the at least one ultrasonic transducer. Each of the plurality of micro-applicator plates has a plurality of apertures and the at least one ultrasonic transducer is configured to vibrate each of the plurality of micro-applicator plates such that at least one material is ejected through the plurality of apertures as atomized droplets. At least one ultraviolet light source is positioned adjacent to the plurality of micro-applicators and the at least one UV light source is configured to irradiate the atomized droplets ejected through the plurality of apertures.
