Some experiments by "cyborgs" are relevant... I remember that one of them added to himself "a sensor that detected Earth's magnetic field." https://www.wired.com/2007/04/esp/ https://www.wired.com/2007/04/esp/ and it seems the experiment has been updated: https://www.theguardian.com/technology/2017/jan/06/first-humans-sense-where-north-is-cyborg-gadget https://www.theguardian.com/technology/2017/jan/06/first-hum... “As we walk down the street there’s radiation, X-rays, infrared and ultraviolet, as well as the electromagnetic field of the planet. So we want to create new senses to become aware of our environment.” and Harbisson, who is colourblind, has an ‘eyeborg’ that allows him to “hear” the light spectrum (including infrared and ultraviolet), while Ribas has a sensor in her elbow that vibrates when an earthquake occurs anywhere in the world.
