Rugged e-skin can heal its cuts and scrapes
Scientists dream of prosthetics and robots with electronic skin that can convey heat and pressure just like the real thing, but there's a big problem getting in the way: the outside world. Bumps and scrapes can damage these sensors, and it's not really practical to toss these skins in the trash when they're no longer useful. UC Boulder researchers hope to fix that. They've developed an e-skin that can communicate temperature and pressure, but is both self-healing and fully recyclable. You could take a cut on a synthetic arm without panicking, and reuse any damaged 'tissue' to make replacements.

Xenoma builds smart clothing for dementia patients
Smart fabric company Xenoma is looking for ways to integrate its technology into our lives, specifically in medical scenarios. The Japanese firm is showing off a set of smart pajamas that can be worn by patients in a hospital, with a specific focus on dementia patients. The idea is that, rather than confining people to rooms or keeping them under observation, the clothing can do the job automatically.

Ultra-thin e-skin could lead to advances in medicine, cool wearable computing (video)
Remember the names Martin Kaltenbrunner and Takao Someya -- that way, you'll have someone to blame when kids start pointing and laughing at gadgets we consider high-tech today. Leading a team of University of Tokyo researchers, they have recently developed a flexible, skin-like material that can detect pressure while also being virtually indestructible. Think of the possibilities: with a thickness of one nanometer, this could be used to create a second skin that can monitor your vital signs or medical implants that you can barely feel, if at all. Also, temperature sensors could be added to make life-like skin for prosthetics... or even robots! Like other similar studies, however, the researchers have a long journey ahead before we see this super-thin material in medicine. Since it could lead to bendy gadgets and wearable electronics first, don't be surprised if your children call iPhones "so 2013" in the not-too-distant future.

Plastic skin lights up on contact, may lead to touchscreens everywhere (video)
Flexible circuitry is frequently a one-way affair -- we've seen bendy displays and touch layers, but rarely both in one surface. UC Berkeley is at last merging those two technologies through a plastic skin whose display reacts to touch. By curing a polymer on top of a silicon wafer, the school's researchers found that they could unite a grid of pressure sensors with an OLED screen; they just had to remove the polymer to create a flexible skin. As the film-like material can be laminated on just about anything, it maylead to touch displays in places where they were previously impractical, or even very thin blood pressure sensors. It could also be easy to produce -- since the skins use off-the-shelf chip manufacturing techniques, commercial products are well within reach.

Researchers say new development could give artificial skin a wider range of senses
We've seen a number of efforts to build a better artificial skin, or "e-skin," over the years, and a team of researchers from the Technion-Israel Institute of Technology now say they've made a breakthrough that could lead to some of the most sensitive e-skin yet. The key development is a new type of flexible sensor that would not only allow the artificial skin to detect touch, but humidity and temperature as well. Those sensors are comprised of gold-based nanoparticles that are just five to eight nanometers in diameter and laid on top of a substrate -- in their research, the scientists used PET, the type of plastic you'd normally find in soda bottles. That substrate conducts electricity differently depending on the way it is bent, which means researchers can adjust its sensitivity just by increasing its thickness. As you might expect, this is all still in the early stages, but the researchers see plenty of possibilities for the future, from bringing a sense of touch to artificial limbs to using the same technology to monitor stress on bridges.

UC Berkeley researchers craft ultra-sensitive artificial skin, robots dream of holding eggs
Researchers and engineers have been toiling on synthetic skins for years now, but most of 'em have run into one major problem: the fact that organic materials are poor semiconductors. In other words, older skins have required high levels of power to operate, and those using inorganic materials have traditionally been too fragile for use on prosthetics. Thanks to a team of researchers at UC Berkeley, though, we're looking at a new "pressure-sensitive electronic material from semiconductor nanowires." The new 'e-skin' is supposedly the first material made out of inorganic single crystalline semiconductors, and at least in theory, it could be widely used in at least two applications. First off, robots could use this skin to accurately determine how much force should be applied (or not applied, as the case may be) to hold a given object. Secondly, this skin could give touch back to those with artificial hands and limbs, though that would first require "significant advances in the integration of electronic sensors with the human nervous system. Dollars to donuts this gets tested on the gridiron when UCLA and / or Stanford comes to town.

Philips develops color e-paper, wants to skin your gadgets with it
Our first reaction to this was to think just how wildly unnecessary "e-skins" are, but then we saw that slide up there and started to see the (electronic) light. Philips appears to have struck upon its own version of Kent Displays' electronic skins, which requires no backlighting, operating by reflecting ambient light instead. Based on similar tech to e-books, this invention is initially targeted at generating colorful covers for things like mobile phones and mp3 players, but it's said to be "highly scalable" and e-wallpapers and light-dimming windows could be on the cards if things continue developing. And of course, no "water cooker" would be left behind. %Gallery-79970%

Japanese researchers craft "e-skin" to let robots feel
The folks at the University of Tokyo have been trying to create more touchy, feely robots for what seems like ages, and they now look to have made some real progress with their so-called "e-skin," which promises to give robots a more human-like sense of touch. To do that, the researchers created a bendable rubber sheet filled with carbon nanotubes, which lets the "skin" conduct electricity even when it's stretched. When combined with sensors, that would let robots feel heat or pressure, which the researchers say is essential "as robots enter our everyday life." They also, not surprisingly, see a whole host of other applications for the technology, including on steering wheels that could judge whether people are fit to drive and in stretchable displays that could start out as a tiny sheet and be stretched to a larger size when you want to watch TV.
