A material applicator for controlling application of at least one material on a substrate includes a housing and an array plate with an applicator array positioned within the housing. The applicator array has a plurality of micro-applicators and each of the plurality of micro-applicators has an ultrasonic transducer, a material inlet, a reservoir, and a micro-applicator plate with a plurality of apertures. The applicator plate is in mechanical communication with the ultrasonic transducer such that at least one material is ejected through the plurality of apertures as atomized droplets when the ultrasonic transducer vibrates the micro-applicator plate.
