Built in LED sterilization UV lamp to achieve "cleanest" doorknob

Tencent digital news, doorknobs may be one of the most dirty objects that we are exposed to in our daily lives. They are touched by many people every day, but often can not be cleaned and sterilized regularly. Today, two senior high school students from the Hongkong Special Administrative Region of China aim at this problem and have developed a new door handle that eliminates the need to use irritating chemicals without regular cleaning and can kill pathogens through built-in ultraviolet lamps.

The two teenagers are Simon Wong and Michael Li, who recently exhibited two kinds of antibacterial technology on the Intel international science and engineering Grand Prix (ISEF) in Pittsburgh, USA: first, the visible surface of the door is made of titanium dioxide -- the natural Wong. The metal oxide itself has antibacterial properties; then, it has a special glass tube that can emit ultraviolet rays, which can emit ultraviolet rays at every time when people open it, thereby effectively destroying the DNA of bacteria that may be attached to the surface of the handle, thereby blocking their reproduction.

In addition to titanium dioxide antibacterial and UV sterilization, this door handle has a clever design: it does not need external power supply or battery installation. A set of built-in transmission devices can turn the door opening and closing actions into electrical energy, thus providing enough power for built-in LED lamps.
