The '2D' imaging sensor might also have some surprising applications for medical devices

Right now, wearables that include cameras are limited in their size by the minimum bulk of those devices. But in the near future, that could change, in part thanks to chemical engineers. Graduate student at the Rice University lab of materials Sidong Lei recently synthesized copper indium selenide (CIS)—a single-layer matrix of copper, indium, and selenium atoms.

This matrix is so small and sensitive to light that it can be put inside a 2D device, rather than requiring 3D components around it. Lei built a three-pixel, charge-coupled device (CCD) to prove it could take an image, but the key is that it can be built in many other sizes and shapes.
