Description

Sandwiched between the , can build a kind of have the capacity to capture the visible light and infrared sensors. Has built a smaller than a fingernail prototype, experts say that the future will be the smart contact lenses ulens graphenesed in soldiers, as well as the need to look around in the dark environment.

Graphene contact lenses lens fully, can like photons of the electrons of the graphene in high-speed movement, is the photon velocity in silicon dozens of times. It can be used as a "hot carrier", can produce the effect of measurement, processing, converted into images.

The team studies a method of graphene for "sandwich" intercalation treatment, the lens as sensitive as silicon digital camera image sensor. They point out that graphene is the preferred material of ultra-wideband photodetector, it can absorb ultraviolet light to far infrared spectrum.
