Engineering researchers from the University of Michigan have developed a one-of-its-kind light detector that operates at room temperature and is capable of sensing the full infrared spectrum all through putting the heat vision technology into a contact lens. Yep. That means, after night-vision goggles it is now the time of night-vision contact lenses. Without the necessity of the bulky cooling equipment, their technology can be incorporated into a super-thin design and therefore finds application in a cellphone or contact lens. Infrared vision has been traditionally used to spot things in the dark or tracking the heat leaks in houses, whereas in the medical field, doctors use it to monitor blood flow. Most conventional cameras can capture just the visible spectrum, but infrared imaging needs different combination of technologies to see near-, mid- and far-infrared radiation all at once. Additionally, they only operate at very cold temperatures.
