phene-Based Light Detectors Add Thermal Vision to Contact Lenses

摘要

New research into graphene-based light detectors that can use the full infrared spectrum has the potential to put heat-vision technology into a contact lens or other devices. And unlike the mid- and far-infrared detectors currently on the market, the detector developed by University of Michigan (Ann Arbor, Ml) engineering researchers doesn't require bulky cooling equipment to work. Thermal imaging is widely used today in military applications for night-vision goggles and cameras, and it's even made some headway into high-end automotive systems, like the night-vision technology from BMW and other carmakers. Infrared light starts at wavelengths just longer than those of visible red light and stretches to wavelengths up to a millimeter long.
