Humans find themselves in another global pandemic, which involves a respiratory virus that can easily spread from the surface to the next victim by touching their face. There is an obvious preventive method to avoid this problem, that is, do not touch the face, at least without first washing your hands thoroughly. However, it is more difficult to develop this new habit than it sounds, so it is a new DIY project of NASA to help.
NASA’s new Pulse wearable necklace is a self-made necklace designed to help the public learn not to touch their faces at least during the COVID-19 pandemic. The space agency did not sell these, but its Jet Propulsion Laboratory has provided its 3D printing concept as open source code to DIYers to manufacture.
The concept is simple-if the wearer raises his hand to the face, the proximity sensor will detect this and use a common button battery to power the necklace to vibrate. This vibration will remind the wearer not to touch his face, thus helping them build the muscle memory needed to form this new behavior.
NASA JPL provides the necessary STL files, as well as the required parts list and assembly instructions. Apart from the 3D printer, the remaining components are easily available, and the pendant should be easily manufactured by someone with basic DIY electrical skills. Of course, some companies are likely to stick to this idea, improve it, and sell their own better versions to the public.
This is just one of the attachments that can help you avoid being infected with viruses, but not enough to protect yourself. Health officials agree to a large extent that everyone should wear a mask in public-preferably a suitable medical mask, but due to shortages of materials, most people wear reusable cloth masks. Similarly, the public is warned to wash their hands often with soap and water, or to use hand sanitizer in public.
