Door handles are dirty, dirty things. Especially ones that you find in public places, where hundreds, if not thousands of hands touch it on a daily basis. And while these door handles may get cleaned every night (hopefully), it's just not enough to make sure that germs aren't being spread about everywhere, getting people sick. That's why we need a door handle that sterilizes itself. And why it's not surprising that when someone designs a concept for one, they win a concept design award.
