Ink coating could enable devices powered by heat

Researchers report that they are closing in on a way to replace batteries for wearables and low-power applications in the internet of things (IoT). The answer lies in an ink coating that enables low-grade heat, which is generated by devices, to be converted to electrical power.

New, highly tunable composite materials - with a twist

Mathematicians have found that they can design a range of composite materials from moire patterns created by rotating and stretching one lattice relative to another. Their electrical and other physical properties can change - sometimes quite abruptly, depending on whether the resulting moire patterns are regularly repeating or non-repeating.
