Daniel Reardon, a research fellow at a Melbourne university, was attempting to build a device that sends out an alarm whenever the wearer unconsciously touches their face.

The idea was to make a necklace with a circuit that could detect the magnetic field, and bracelets containing powerful neodymium magnets.
That way, every time you go to touch your face, you would trigger the alarm
Instead, it did the exact opposite, buzzing non-stop until Reardon moved his hands closer to his face.
