Skin-inspired haptic-memory devices, which can retain pressure information after the removel of external pressure by virtue of the nonvolatile nature of the memory devices, are achieved. The rise of haptic-memory devices will allow for mimicry of human sensory memory, opening new avenues for the design of next-generation high-performance sensing devices and systems.

Tannic acid (TA), a large polyphenolic molecule, has long been known for using in food additive, antioxidants, bio-sorbents, animal feeding and adhesive making due to its intrinsic properties such as...

Water molecules form layered structures inside graphene bilayers and ultra-high pressure-driven flow rates can be observed.
