NASA knows the importance of not touching your face during this pandemic, so they created PULSE, or a 3D-printed wearable device that pulses, or vibrates, when a person’s hand nears that area. Since entire project is open source and available on Github, it’s simple as well as affordable technology that can easily be reproduced should you have a 3D printer as well as basic technical knowledge. Read more for a video, additional pictures and information.
It uses an infrared proximity sensor to detect when a person’s hand is nearing their face, while a vibration motor vibrates out an alert if that happens, and the response grows increasingly stronger as your hand gets closer. Each one is powered by 3V coin batteries, which are readily available both in stores and online. More informatioon here.
The objective of Pulse is to minimize the spread of the COVID-19 virus, which can be transmitted if an individual touches an infected surface with their hand and then touches either their eyes, nose or mouth,” according to a NASA press release.
