Researchers have succeeded in producing a coating material that can be written on using UV light and the writing erased again using oxygen. Changes to rewritable paper could help reduce paper waste in a wide variety of applications.
To create their chip, researchers removed the four main time-consuming culprits in the traditional computer chip: the conversion of optical to electrical signals, the need for converting the input data to binary format, a large memory module, and clock-based computations.
