A first-ever stretchy electronic skin could equip robots and other devices with the same softness and touch sensitivity as human skin, opening up new possibilities to perform tasks that require a great deal of precision and control of force.

The new stretchable e-skin, developed by researchers at The University of Texas at Austin, solves a major bottleneck in the emerging technology. Existing e-skin technology loses sensing accuracy as the material stretches, but that is not the case with this new version.

“Much like human skin has to stretch and bend to accommodate our movements, so too does e-skin,” said Nanshu Lu, a professor in the Cockrell School of Engineering’s Department of Aerospace Engineering and Engineering Mechanics wh...

Bacteria ‘Nanowires’ could help Develop Green Electronics

Bacteria 'nanowires' could help develop green electronics
Structure of γPFD filaments and incorporation of heme to make conductive nanowires. a) Filament assembly of γPFD through β-sheet domains, and b) proposed binding of heme molecules to the coiled-coil domains to form γPFD-heme nanowires. c) Protein-ligand binding isotherm with 30 µm of γPFD and varying concentration of heme, which indicates a stochiometric ratio of ≈1 heme per γPFD subunit in filaments. d) TEM image of the γPFD-heme nanowires.

A research team has created an innovative method to control tiny magnetic states within ultrathin, two-dimensional van der Waals magnets — a process akin to how flipping a light switch controls a bulb. Imagine a future where computers can learn and make decisions in ways that mimic human thinking, but at a speed and efficiency that are orders of magnitude greater than the current capability of computers.

A research team at the University of Wyoming created an innovative method to control tiny magnetic states within ultrathin, two-dimensional (2D) van der Waals magnets — a process akin to how flipping a light switch controls a bulb.

“Our discovery could lead to advanced memory devices that store more data and consume less power or enable the development of entirely new t...

Researchers have found two novel types of attacks that target the conditional branch predictor found in high-end Intel processors, which could be exploited to compromise billions of processors currently in use.

The multi-university and industry research team led by computer scientists at University of California San Diego will present their work at the 2024 ACM ASPLOS Conference that begins tomorrow...
