NASA designed a vibrating necklace to help you stop touching your face
If you still can't stop touching your face as the coronavirus outbreak drags on, NASA's Jet Propulsion Lab has a wearable for you. The PULSE is a pendant that you can hang from your neck like a necklace, but it's not just decorative.
When your hand gets close to the device it starts to vibrate. That's supposed to remind you to stay away from your face zone. Three teammates at the lab developed the vibrating necklace to work with other coronavirus measures, like hand-washing and mask-wearing.
NASA doesn't have an Etsy shop or anything, so the design instructions to make the PULSE are available free for anyone. You just need a 3D printer, a soldering tool, some wires, a motor, coin battery, and other materials.
