Pulse is an open source NASA project that, with a few pieces and a 3D print, allows you to build a pendant that vibrates when the hands come close to the face.
There are actions, including touching our face, that we do without realizing it. Unfortunately, however, one should limit as much as possible to touch one’s nose, eyes and eyes and therefore, more generally, the face in order not to carry viruses and bacteria, which are in our hands, inside the body.
Obviously this good hygienic norm, valid in all circumstances and at all times, has become of fundamental importance especially this year while the whole of humanity is fighting against the COVID-19 pandemic generated by the new coronavirus.
So here is a team of three from the Jet Propulsion Lab (JPL) of NASA has developed Pulse, a wearable pendant composed of simple and affordable parts and a transparent case that contains them which is achievable with a 3D printer.
Pulse detects movement and vibrates if the hands come close to the face.
Pulse detects the movement of the person using an infrared proximity sensor with a range of up to 30 cm and starts vibrating more and more intensely the closer the hands are to the face.
The parts list and assembly instructions are available Open Source on the Github platform for individuals or companies who want to replicate, improve and perfect Pulse.
Ideally, we expect the public to further develop this project and make it easily available for distribution
in fact, the agency writes.
Pulse does not replace medical devices and is not approved by the FDA
NASA is also keen to point out that the device cannot replace medical devices and is not approved by the FDA since NASA’s Jet Propulsion Laboratory cannot in fact provide any medical guarantees, but
offers explanations for building the device in good faith to help healthcare providers and others prevent the spread of coronavirus and treat patients.
It is not the first time that the engineering skills of the Jet Propulsion Laboratory have been used to serve the community to deal with the COVID-19 pandemic, a group of scientists have built a fan prototype called VITAL which we talked about in this article:
