Doctors and scientists from all over the world are working day and night to stop the spread of coronavirus infection. In such a situation, the only way to avoid this is to keep as much distance from each other as possible.
In this endeavor, the National Aeronautics and Space Administration (NASA) has developed a three-D printed necklace that alerts you when someone comes in contact.
How NASA’s 3D necklace works
This special necklace is named PULSE by NASA. It tracks hand movements and also prohibits you from touching your face. If you try to touch your face while wearing this necklace, then a vibration alarm will ring. As your hand moves closer to the face, the vibration will increase in it.
Use of proximity sensor
NASA’s Jet Propulsion Laboratory has designed the PULSE necklace. It uses a 12-inch range proximity sensor. At the same time, it also has a motor for vibration which has been paired with a small 3V battery. NASA says it shows accurate results when keeping this necklace six inches below the neck.
