There are some wearables out there in the world that are making claims around COVID-19 and their ability to detect it, prevent it, certify that you don’t have it and more. But a new wearable device from NASA’s Jet Propulsion Laboratory might actually be able to do the most to prevent the spread of COVID-19 — and it’s not really all that technically advanced or complicated.

JPL’s PULSE wearable uses 3D-printed parts and readily available, affordable electronic components to do just one thing: remind a person not to touch their face. JPL’s designers claim that it’s simple enough that the gadget “can easily be reproduced by anyone regardless of their level of expertise,” and to encourage more people and companies to actually do that, the lab has made available a full list of parts, 3D modeling files and full instructions for its assembly via an open-source license.
