AI Technical Summary

Technical Problem

Existing technologies fail to identify and effectively sterilize or inactivate microorganisms, particularly those adhering to fixtures in indoor spaces, due to limitations in detecting all locations of potential infection risk, including areas where droplets are dispersed.

Method used

A sterilization/virus inactivation device equipped with a microorganism-attached portion identification unit to identify areas where microorganisms adhere, a substance generation unit to produce disinfecting substances, and a transport unit to deliver these substances directly to the identified areas, enhancing the efficiency of sterilization and inactivation.

Benefits of technology

The device efficiently targets and treats high-risk areas by delivering disinfecting substances directly to microorganism-attached portions, ensuring thorough sterilization and inactivation of bacteria and viruses, thereby reducing the risk of infection.
