Self-repairing shoes may be a reality thanks to 3D-printed rubber
Shoes will invariably wear out with enough use, but scientists might have found a way to delay the shopping trip for their replacements. A USC team has created a self-healing 3D-printed rubber that could be ideal for footwear, tires and even soft robotics. The effort involves 3D printing the material with photopolymerization (solidifying a resin with light) while introducing an oxidizer at just the right ratio to add self-healing properties without slowing down the solidifying process.
MIT engineers make beaver-inspired wetsuit to keep surfers warmer
Large oceangoing creatures, like whales and seals, keep warm with thick layers of blubber. But smaller mammals like beavers and otters have a different method of insulation: Their dense fur, which traps warm air bubbles to separate their body from cold waters. MIT engineers have devised a wetsuit featuring a similar hairy layer made of rubber to insulate divers and surfers.
Researchers develop ice-repellent coating for windshields and more
Having to scrape ice off your windshield in freezing temperatures before heading off to work is awful. When ice builds up on airplanes and other equipment, it can go from being a nuisance to causing serious danger. To combat icy buildup, researchers at the University of Michigan developed a spray-on ice repellent coating that can be applied to equipment, aircraft and car windshields to make removing the frozen stuff a breeze. In fact, the team of engineers say all it takes to clear off a treated surface is the force of gravity or a light breeze thanks "iceophobic" material.
Stretchable square of rubber doubles as a keyboard
There's a whole branch of science that's dedicated to turning flexible surfaces into sensors that can be used as an artificial substitute for skin. These materials could then be used to give robots a sense of touch, or even to restore feeling for people with artificial prostheses. Researchers at the University of Auckland have taken the concept in a slightly different direction after building a square of soft, stretchable rubber that pulls double-duty as a keyboard. It's hoped that the technology can be used to create foldable, rollable input devices, which reminds us of Nokia's twisty-stretchy phone concept from way back when.
Ricoh invents super-efficient power-producing rubber
No, this is not an image of a delicious Fruit Roll-Up, it's actually a unique new flexible material from Ricoh that can create electricity from pressure and vibration. Dubbed "Energy-Generating Rubber," this piezoelectric mat combines the best features of existing ceramic and polymeric materials; high energy output and flexibility, respectively. In fact, this new rubber produces just as much power as ceramic does while surpassing the flexibility of polymeric materials, according to Ricoh. What's more, it is more easily produced than either existing form of piezoelectric.
Canon recalls 68,200 EOS Rebel T4i DSLRs, says rubber grips can lead to skin rash
We've covered our fair share of product recalls over the years, but this one almost certainly takes the cake when looking at pure zaniness. Canon has recalled its EOS Rebel T4i -- some 68,200 units -- "due to a risk of allergic reaction." You read that right. As the story goes, a chemical used in the camera's rubber grips "can result in a reaction that changes the grips from black to white and poses a risk of skin irritation to the consumer," and while the company has only received a single report of a consumer developing a "minor rash" after contact, that's obviously enough to issue to recall. It involves T4i units with a 12-digit serial number that contain a second digit that is a "3" or "4" and a sixth digit that is a "1." If that's you, you're advised to stop using the camera and ping Canon USA to have replacement rubber grips installed free of charge. Specifically, you can ring 855-902-3277 and be prepared to be placed on hold for the better part of your adult life.
LG Optimus Vu launches in Korea, gets priced
LG's 5-inch smartphone has finally arrived -- at least over in Korea. While 4:3 ratio display raised a few eyebrows during its debut at MWC, the IPS display, lightweight frame and stylus has us chasing after a review model to give it the full run-down. Anyone in LG's homeland can beat us to the punch -- it's now on sale priced just under the Galaxy Note, a device that's been around for a few months. Expect to pay 990,000 won ($890) for a carrier-free version, but importers should 'note' that they won't be able to take advantage of that built-in TV tuner. We're still sniffing out details on prices and launch dates for the US. Hopefully, the international model will arrive with a rubberdium stylus -- we just want to know what rubberdium is.
LG Optimus Vu officially revealed ahead of MWC with stylus, 1.5GHz CPU (Updated)
Similar to its pre-CES reveals, LG just couldn't wait for Mobile World Congress to get underway on the 27th before showing off its new Optimus Vu handset. These new pics offer a much clearer look at its 4x3 aspect ratio, 1024x768 res, stylus-friendly 5-inch IPS LCD display, while the official specs confirm rumors it would pack a 1.5GHz dual core CPU, 8MP camera, LTE, 2080mAh battery and Android 2.3 in a slim 8.5mm thick frame. An upgrade to Ice Cream Sandwich is promised within three months of its launch, currently scheduled for March on Korean carriers SK Telecom and LG+. Check the gallery for a few more glamour shots of this new Galaxy Note competitor, and see if wider truly is better.Update: You'll find a few more official pictures in the gallery below and the English PR with details on its "QuickClip" hotkey for one-button screenshots and memos and the "Rubberdium" stylus after the break, plus a quick size comparison vs. the Note, Galaxy S II Global and iPhone 4S.
Robot skin captures super detailed 3D surface images
Remember those awesome pin art toys where you could press your hand (or face) into the pins to leaving a lasting impression? Researchers at MIT have taken the idea one (or two) steps further with "GelSight," a hunk of synthetic rubber that creates a detailed computer visualized image of whatever surface you press it against. It works as such: push the reflective side of the gummy against an object (they chose a chicken feather and a $20 bill) and the camera on the other end will capture a 3-D image of the microscopic surface structure. Originally designed as robot "skin," researchers realized the tool could be used in applications from criminal forensics (think bullets and fingerprints) to dermatology. The Coke can-sized machine is so sensitive, it can capture surface subtleties as small as one by two micrometer in surface -- finally solving the mystery of who stole the cookies from the cookie jar. (Hint: we know it was you Velvet Sledgehammer).
Hard Candy Street Skin for iPhone 4 makes for a decent everyday case
Hard Candy, the folks behind the Street Skin line of tire tread-like rubber cases for Apple's iDevices we've talked about before, also has an iPhone 4 variant. The Street Skin for iPhone 4 is made of TPU, a shock absorbing semi-flexible rubber, which encases the iPhone leaving only the screen exposed. Along the sides there are cut-outs for the volume buttons and mute switch, while the top and bottom have holes for the power button, headphones port, dock connector and the speakers. On the back, the camera and LED flash are left exposed for snapping pictures. The case is about 2.5 mm thick, making it pretty slimline for a rubber case and allowing it to fit in most non-custom docks without having to remove the case. It wraps around the front of the iPhone 4 as well, meaning that when laid flat on a table the screen is kept off the deck preventing scratches. The TPU gives the case a grippy texture, but thankfully not enough to cause severe pocket torsion, where you simply can't get the iPhone out of your pocket due to friction. The rubber itself has a distinctive crisscross tire tread pattern that makes it stand out from the usual cheap silicone-based fodder you see on eBay (check out the gallery below to see it in its full glory). The corners are pretty well protected, which should help if, heaven forbid, you manage to drop your precious glass iPhone. I wouldn't advocate that the Street Skin gives great impact protection, but with a bit of luck the TPU should provide enough energy absorption to prevent the screen cracking for low height drops. %Gallery-127973% Verdict Overall the Street Skin for iPhone 4 offers fairly good protection without adding huge amounts of bulk. Some might not like the tire tread patterning, or the rubber texture, but it's available in pink, white and black for both the CDMA and GSM variants of the iPhone 4 from US$29.95 and makes a decent everyday case.
Hard Candy Street Skin for iPad 2 covers all corners
Hard Candy cases, known for their sex-sells approach (just take a look at their site), has brought their Street Skin line to the iPad 2. Designed as thin yet rugged cases for Apple's iDevices, the Street Skin cases are made of TPU and feature a tire-like design with a raised grip pattern across the surface. The Street Skin for the iPad 2 is no exception, covering the iPad in a semi-flexible rubber that's about 3 mm thick. The case wraps tightly around the back and sides of the iPad with a lip covering the front edge of the screen making sure that all the corners and edges are covered nicely. There are good-sized cutouts for the buttons, mic, ports, speaker and camera meaning you're not losing any functionality with the case on. What makes the Street Skin standout is the hinged front cover design. The front flap fits into the front lip of the case on the screen, ensuring the entire glass front of the iPad 2 is covered save for two small holes where the front lip of the case is shaped to allow access to the Home buttons and the ambient light sensor. When not in use the front flap is secured by two clasps at the top and bottom right corners of the cover. Once you need access to that gorgeous screen you unhook the clasps and fold the cover back around the rear of the iPad, moving the hinge all the way to the rear of the iPad and allowing the flap to be secured across the back using the same corner clasps. Once in place the flap is properly secured out the way, allowing you to get on with your business without having to worry about it. It's a simple yet very effective design. I have doubts as to how long the clasps will last as the corner straps on the front flap are pretty thin, but after a decent period of rigorous testing there doesn't seem to be any wear and tear to them. %Gallery-127557% Verdict The Street Skin for the iPad 2 is a solid case offering. It covers the important parts, leaves access where needed and covers the screen well with it's front flap that gets out of your way when the iPad is in use. The tire-like styling may not be to everyone's taste however, and I doubt the case will do much if you dropped the iPad 2 from any great height save for preventing scratches. I've also noticed that the reverse of the front flap, the bit that touches your screen, is prone to picking up dirt, dust and fingerprints and helpfully transferring them to your screen when you close the case. If kept clean with a cloth, everything is well however. If you want fairly decent protection without adding too much bulk, then the Street Skin for iPad 2 delivers for around $39.95 plus shipping. It's available in black, white and pink, with the white one we had in for testing looking a lot like the classic Storm Trooper armor.
Apple will now replace your MacBook's bottom
Apple has debuted a new support program called (quite reasonably) the MacBook Bottom Case Replacement program. As 9to5Mac notes, there's been an issue with the rubber bottom part on some recent MacBook models where some glue problems may separate the rubber pad from the actual MacBook case. If you have had such an issue with a MacBook sold in the past few years, Apple will be happy to replace it at any Apple Store. And if you don't want to bother with coming in, you can even order a replacement kit online, then just put the new case on yourself. It's not a huge deal, of course, and Apple says that if you're not having the problem, you obviously don't need to replace your case, but it's good to know that Apple's got a way to deal with even a small hardware issue like this.
Clickfree C2 Rugged hard drive can fall down, backup
There's just something about the phrase "built to strict U.S. military standards" that makes us want to go positively medieval on a rugged device. Sadly, the aforementioned qualifier doesn't mean that Clickfree's new C2 Rugged Back-up Drive is capable of withstanding, say, a hail of gunfire, but the rubberized disk will continue to work after being dropped from four feet. The peripheral also features the company's Easy Run software, which will start automatically backing up your PC when you're done showing that storage device who's boss. The 500GB C2 is available now through Clickfree's site for $140 -- or $100, if you're one of the lucky 100 first people to buy, so maybe buy two, in case you go a little overboard.
Planex capacitive stylus mocks Steve Jobs, all the way to the bank
In the past, our coverage of Planex has largely been relegated to storage devices and wireless access points, but now the company has entered one of the most exciting businesses of all: breaking poor Steve Jobs's heart. That's right, the company has meddled with the natural order of the universe by releasing new smartphone styli. They come in two colors -- black and white, naturally -- and two lengths: 4.2- or 1.6-inches, with soft rubber tips measuring 8mm and 9mm, respectively. The pens will run you ¥1,200 ($15) or ¥1,000 ($12), which is more or less on par with the current suggested price of the Pogo sketch stylus -- well, that plus airfare to Japan to pick one of these things up. But hey, it still beats a hunk of deli meat, right?
Ask Engadget: best latex-free mouse and keyboard solution?
We know you've got questions, and if you're brave enough to ask the world for answers, here's the outlet to do so. This week's Ask Engadget question is coming to us from Cris, who can't seem to find a latex-free mouse that he needs to prevent allergic reactions. If you're looking to send in an inquiry of your own, drop us a line at ask [at] engadget [dawt] com. "I work in an office environment for ten hours a day in front of a computer where my right hand spends most of it's time on my wireless Microsoft Intellimouse Explorer 2.0. It's a mouse I've loved, but there's an issue. I have discovered that I'm allergic to the rubber latex used in the mouse. Although I have not had a tough time finding posts online from people complaining of the same problem, I have had a very difficult time finding a solution. I need a latex-free mouse, preferably with similar features to the Intellimouse I love so much. It's easy to find many things in a latex-free variety; obviously mice aren't in that group. Thanks!" So, any suggestions for Cris? Quite a few folks are allergic to latex rubber, and it's borderline impossible to believe that no latex-free mouse lives in a world chock full of options. If you've managed to uncover a gem that fits the bill (or a particular keyboard, while we're on the subject), drop a hint in comments below.
Gadget bandz bring gear lust to tween wrists
You know about Silly Bandz, right? Well, maybe you don't have subscriptions to Tiger Beat and spend your evenings at home alone on Bieber message boards like we do, so allow us to explain. They are rubber bands that are shaped like things--unicorns, peace signs, hamburgers, aliens, emoticons--traditionally worn on the wrists, and eventually traded with like-minded collectors. They are very popular in the 8 - 12 demographic. You might relate them to Pogs, slap bracelets, Lisa Frank pencils, and baseball cards. Now that you know what's up, the point is that they are now available in gadget shapes: iPod nano, laptop, iPhone 3G, NES controller, digital camera, and the "most collectible" iPad...er, "tablet." That is all.
iPhone 4 gets a $1 alternative to pricey Bumpers
If you ask us, Apple should be giving away free bumpers, lollipops, and anything else it can think of to keep its otherwise loyal followers from revolting. But the Great Bitten One isn't doing any one of those things, and most of us are stuck either having to pony up $30 for the official salvation from self-inflicted signal harm or looking out to the grey markets. Entering this morose situation with a bit of ingenuity is Oliver Nelson, who alerts us to the fact that rubber wristbands of the sort your favorite cyclist wears are apparently an almost perfect fit when stretched around the 4's antennae. He advises that a 1.125-inch long by 0.125-inch wide incision (into the unstretched band) is necessary to keep the 30-pin port and speakers open, but otherwise it seems like a pretty effortless and dirt cheap way to avoid all this drama.
Replica tabards and banners from Windlass Studios
Blizzard has announced that they've partnered with a company called Windlass Studios to release real-life versions of a couple popular in-game banners and tabards. $40 will get you a banner of the Alliance or Horde, while $80 will get you a real-life faction tabard to wear. Each of the pieces is apparently 100% cotton, and silkscreened with the familiar faction insignia. Very interesting -- we've seen some nice fanmade pieces before, but these are commercial releases bearing official logos. The company has also released a latex rubber version of Frostmourne -- it's not quite as nice as the Epic Weapons metal version, but then again, it's $149, and the metal version is over $400. I still wouldn't spend over $100 on a rubber sword, but hey, if that's your thing, there you go. And speaking of spending money on rubber costumes, the Blizzard store is also chock full of Halloween costumes this year, and there are a few other masks, including Illidan and a new Draenei mask, floating around the Internet for purchase as well.
Tangible 3D UI being developed in Japan (video)
People have been trying to sell us 3D this and 3D that for ages, but for the most part it's always been the same flat surface we're looking at and poking with our fingers. Some restless souls in Japan, however -- including Engadget's very own Kentaro Fukuchi -- have begun developing a way for computers to recognize a person's interactions with real objects and to respond accordingly. The essence of this new technique is to use translucent rubbery objects, whose diffraction of specially polarized light is picked up by a camera. Thus, relatively subtle actions like squeezing and stretching can be picked up by the different light results produced. Still in the early stages of design, the system is hoped to assist in surgery training, though we've got video of its more fun potential uses after the break.[via New Scientist]
Flexible, stretchable, rubbery OLED prototype shown off in Tokyo
Electrical engineering researchers at the University of Tokyo have developed a flexible, stretchable OLED that acts something like rubber, and does not tear or break when stretched. The material is produced by spraying a layer of carbon nanotubes with a fluoro-rubber compound, creating a rubbery, conducive material. The current, monochrome display prototype has a resolution of just 256 pixels, is 10-centimeters square, and can apparently be folded about 1,000 times with out falling apart, tearing, or imploding. The team is presenting its findings in the British science journal Nature Materials this month.[Via Slashgear]
