"... stops people touching their faces during the coronavirus outbreak. Dr Daniel Reardon, a research fellow at a Melbourne university, was building a necklace that sounds an alarm on facial contact, when the mishap occurred on Thursday night.... 'I had a part that detects magnetic fields. I thought that if I built a circuit that could detect the magnetic field, and we wore magnets on our wrists, then it could set off an alarm if you brought it too close to your face. A bit of boredom in isolation made me think of that.... I accidentally invented a necklace that buzzes continuously unless you move your hand close to your face.... After scrapping that idea, I was still a bit bored, playing with the magnets. It’s the same logic as clipping pegs to your ears – I clipped them to my earlobes and then clipped them to my nostril and things went downhill pretty quickly when I clipped the magnets to my other nostril.'"
