We develop instant, effective, cheap and user-friendly UVC / Far-UVC disinfection devices, and iOS-based mobile application that assists usage of the devices.
A tiny stick device with UVC LEDs that can be easily attached to a mobile phone by a magnetic sticker for virus disinfection will be designed. The application installed in the mobile phone will guide the user on disinfection time and progress.
A portable Far-UVC disinfection device will also be designed to guide the user to disinfect the target in the shortest time.
The system will integrate two special technology features. (i) The device will integrate a graphite planar heater and temperature sensors for providing a higher temperature for disinfection of human body. The controlled temperature will speed up the Far UVC disinfection efficiency and ensure that it will not overheat and harm the human body. (ii) A compact integrated Far-UVC source will be used in the device for providing heat distribution features and a cheaper solution. This new source requires the programme system APP to provide a controllable voltage pulse supply in order to maximize its performance.
