Do you, like many people, avoid touching door handles in public toilets because they might be covered with germs?
That precaution may no longer be necessary in the near future, thanks to an invention by two Hong Kong students, Headline News reported Thursday.
Wong Sum-ming and Li Kin-pong, Secondary 5 students at the Church of Christ in China Tam Lee Lai Fun Memorial Secondary School, were awarded a gold medal at the 44th International Exhibition of Inventions of Geneva for a self-disinfecting door handle.
The glass handle, coated in titanium dioxide and powered by a self-charging dynamo, kills germs with UV light.
So far, two factories have expressed interest in manufacturing the door handle.
Sum-ming has suffered from dyslexia since Primary 1, but that has proven not to be too much of an obstacle for him.
He read a lot of academic papers before coming up with the invention with his schoolmate.
It was a challenge at first, he said, but he later discovered that many of the terms used in those papers were more or less the same.
