NASA has developed an anti Coronavirus(COVID-19) necklace (Pulse)

NASA's Jet Propulsion Laboratory has developed a necklace that aims to reduce the spread of the coronavirus by warning people when they are about to touch their face.

A necklace that aims to reduce the spread of coronaviruses, and encourages people to be careful when touching their faces.
Using an infrared sensor, the device detects a hand that is too close to the face. As soon as movement appears, a small motor is triggered inside the necklace.

Pulse necklace developed by NASA

Called Pulse, the wearable pendant is a 3D printed pendant that uses a proximity sensor and vibrates if the hand approaches. The vibrations get stronger the closer your hand gets to your face.

"The goal of PULSE is to minimize the spread of the COVID-19 virus, which can be transmitted if an individual touches an infected surface with his or her hand and then touches the eyes, nose or mouth," NASA said in a booklet on the wearable.





  • NASA has made it clear that it cannot be used instead of a mask and other personal protection measures designed to protect against coronavirus, it can only be used with them.
  • This concept is a response to how often hand contact occurs during the day, a subconscious behavior that can be overlooked and difficult to correct.



COVID-19 CDC guidelines

To protect yourself from COVID-19, you can follow the guidelines established by the US Centers for Disease Control and Prevention: Wear a face mask, practice social distancing, disinfect surfaces, wash your hands frequently, and avoid touching your face.
The CDC says the corona virus is transmitted by respiratory droplets that spread when an infected person coughs, sneezes, or speaks. These droplets can fall on the surface or into the mouth or nose of nearby people.

NASA said that Pulse is designed to be accessible and easy to make so that it can be reproduced by anyone. The assembly instructions and a parts list are open source and free for public use.  

Apple, Samsung and Google, among other technology giants, have updated their portable products to curb the proliferation of COVID-19.

Samsung and Google have hand wash timers for their watches. Apple has also introduced a number of features for WWDC, including a hand washing timer for Apple Watch and face masks for Memoji to promote healthy habits.
