The new NASA device will warn you if you try to touch your face.
A device worn on the body will vibrate when a person’s hands are brought to his face. Avoid touching the face with dirty fingers is considered the most important means of preventing coronavirus and other respiratory infections.
A device known as “PULSE” will start the vibrating motor and LED. “The tactile feedback from the vibrating motor mimics the jolt, reminding the wearer not to touch his face in order to reduce the potential risk of infection,” the developers say. You can create the device yourself using a 3D printer, the agency will make the drawings open.
