NASA introduced 3D printed necklace
Doctors and scientists from all over the world are working day and night to check the infection like corona virus. Billions of rupees are being spent for the corona vaccine, but today even after so many months, the corona vaccine is not ready. At the same time, the only way to avoid this is to keep as much distance from it as possible. Social distancing is the biggest weapon to avoid infection.
Many types of ninja techniques are also being used for this. In this endeavor, the National Aeronautics and Space Administration (NASA) has prepared a three-D printed necklace that alerts anyone when they come in contact. . And this necklace tracks hand movements and refuses to touch the face.
If you are wearing this necklace and are trying to touch the face, then the vibration alarm will ring. As your hand moves closer to the face, the vibration in it will continue to intensify. The PULSE is designed by NASA's Jet Propulsion Laboratory. And it has used a 12 inch range proximity sensor. It also has a motor for vibration. Its case has a 3V battery. NASA has said that if you place it six inches below the neck, it will give accurate results.
