TL;DR: A highly scalable and ultrafast production of graphene-based flexible, washable, and bendable wearable textile sensors that show excellent temperature sensitivity, very good washability, and extremely high flexibility are reported.

TL;DR: In this article, two insulating crystals of hexagonal boron nitride stacked at small twist angle were observed to have a bilayer-thick ferroelectric with oppositely polarized dipoles in neighbouring domains.

TL;DR: These results add piezoelectricity to the known properties of monolayer hBN, which makes it a desirable candidate for novel electromechanical and stretchable optoelectronic devices, and pave a way to control the local electric field and carrier concentration in van der Waals heterostructures via strain.

TL;DR: Moiré superlattices generated by twisted insulating crystals of hexagonal boron nitride are shown to have a ferroelectric-like character, attributed to strain-induced polarized dipoles formed by pairs of interfacial bor on and nitrogen atoms that create bilayer-thick ferro electric domains.

TL;DR: In this paper, the authors present a route to spectrum reconstruction at all energies by using graphene which is aligned to two hexagonal boron nitride layers, one can make electrons scatter in the differential moire pattern which results in spectral changes at arbitrarily low energies.
