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.

A gardening sprinkler may include a sprinkler base, and two first main bodies are respectively formed at two lateral sides of the sprinkler base while two second main bodies are respectively formed at the front side and the rear side of the sprinkler base, so as to form the sprinkler base in a firm-structure frame shape. The first main bodies and the second main bodies are formed in hollow with thin shell, and a plurality of hollow holes are formed thereon to reduce the weight of the sprinkler base and lower the cost of production, thereby achieving the effects of environmental protection and energy saving. The hollow holes are adapted to reserve space to allow a turf to well grow therefrom.

An atomizer for applying a coating includes a nozzle plate, an actuator, and an acoustic focusing device. The nozzle plate defines at least one aperture. The actuator is configured to oscillate to form pressure waves within a fluid to eject the fluid from the nozzle plate. The acoustic focusing device focuses the pressure waves toward the apertures.
