Innovative Ultrasonic Spray Methods for Indoor Disinfection

This study addresses the challenge of dispersing disinfectant liquids for sanitizing people, indoor spaces, vehicles, and outdoor areas. Fine aerosol sprays with a large surface area of particles are considered the most promising solution for such tasks. The study identifies shortcomings in current spraying methods and highlights the potential of ultrasonic liquid atomization for improving disinfection processes. Innovative specialized ultrasonic atomizers are introduced, capable of producing aerosols with the required droplet size and efficiency from disinfectant liquids of varying viscosities, including those containing silver nanoparticles.
