NASA has released open-source instructions for a 3D-printed necklace designed to help you stop touching your face. We’ve heard time and time again that we shouldn’t touch our mush with our fingers to limit our chances of contracting COVID-19. However, it’s not always easy to avoid that reflex.
To remind you to keep your mitts at bay, three engineers at the agency’s Jet Propulsion Lab created Pulse. The necklace has a proximity sensor with a 12-inch range and a coin vibration motor, which activates when you move your hand towards your head. The closer your fingers are, the more intense the vibrations get.
