Electronics can grow on trees thanks to nanocellulose paper semiconductors

A team in has created a nanocellulose paper semiconductor with both trans-scalability of structural design and wide electrical property tunability. The structure and function of the nanopaper semiconductor could be customized according to the desired use, allowing diverse applications as a wearable water-vapor-selective sensor and an enzymatic biofuel cell electrode for energy generation. This achievement is expected to open new doors for sustainable electronics that are completely derived from plant materials.
