Development of Door Handle Sterilizer Design using UV LED and AI Voice Recognition

This research aims to study the design and development of a door handle sanitizer using UV LEDs and AI technology.In this study, a prototype was designed to optimize the disinfection effect using 275 nm wavelength ultraviolet light emitted diodes (UV-LEDs).Furthermore, a circuit was designed to incorporate features such as artificial intelligence-based body sensing, akin to Wav2vec 2.0, to detect individuals intending to use the door handle.It includes a timer setting function for periodic sterilization and disinfection at specified intervals, a UV LED sterilization capability to eliminate various bacteria, a repositioning feature during sterilization if human presence is detected, a forced repositioning function, a dual-use functionality for both battery and adapter and a display for remaining sterilization time with an optional display selection feature.Utilizing computer-aided design software, 3D printing, Arduino, Wav2vec 2.0, and other technologies, prototypes of the door handle sanitizer using UV LED were systematically created.The results of this research focused on the operational principles and aesthetic aspects of door handle sanitizer using UV LED.A performance evaluation and disinfection efficacy assessment of a door handle sanitizer using UV LED was planned for the future.Additionally, various applications of AI voice recognition technology were explored.
