NASA showed a pendant that interferes with the spread of coronavirus and protects its owner from bacteria
The device is a pendant to be worn around the neck. When bringing the hand to the face, this movement captures the IR sensor, after which the suspension begins to vibrate.
The development was called PULSE, it is noted that it can be made on a 3D printer.
The creators provided a complete list of parts, simulation files, and open-source instructions.
Scientists note that the suspension does not completely protect against COVID-19, but only helps to form a useful habit that reduces the risk of infection.
