On June 29, according to media reports, NASA's Jet Propulsion Laboratory developed a necklace,Vibration warning will be issued when the hand is about to touch the face to reduce the spread of new coronavirus。
The wearable device, called pulse, is a 3D printing pendant, the report said. The pendant has a built-in sensor,When the hand is close, it vibrates, and the closer it is, the stronger the vibration is。
People touch the face with their hands is usually subconscious behavior, which occurs frequently in a day, but is often ignored. The pulse necklace is designed to prevent people from touching the face and minimize the spread of the new coronavirus. If a person touches a person or object with a new coronavirus by hand and then touches the eyes, nose or mouth, there is a risk of infection.
The Centers for Disease Control and Prevention (CDC) has also developed guidelines, such as advising people to wear masks, keep social distance, wash their hands frequently and avoid touching their faces.
NASA said,Pulse is easy to make and reasonable in price. Assembly instructions and parts lists are also open source and can be used by the public free of charge。 In addition, technology giants such as apple, Samsung and Google have also configured their wearable devices with updates such as hand washing timers to help reduce the spread of the virus.
