A group of researchers led by Dr Ravinder Dahiya at the University of Glasgow, Scotland, has found a way to produce large sheets of graphene, borrowing materials from the manufacture of lithium-ion batteries. The cost of this substrate, which directly relates to the cost-of-production of the graphene itself, is around 1/100th of the material previously used. Graphene has been hailed as a 'wonder material' since it was first isolated from graphite in 2004. Graphene is just a single atom thick but it is flexible, stronger than steel, and capable of efficiently conducting heat and electricity.

Researchers from Rice University (Houston, Texas) have prepared a research paper on Flatcam, a camera system that replaces lenses with a coded mask and computation. The Flatcam has similarities to lensless image sensor being developed by Rambus, which replaces the lens in a conventional camera with a diffraction grating and computation (see Rambus develops lensless image sensor for IoT). However, the Flatcam does provide a complete optical reconstruction of the given scene, while the Rambus system does not as it is intended for use by machines.
