Origami-like soft robot can lift 1000 times its weight
Soft robotics allow machines to move in ways which mimic living organisms, but increased flexibility usually means reduced strength, which limits its use. Now, scientists at MIT CSAIL & Harvard have developed origami-like artificial muscles that add much-needed strength to soft robots, allowing them to lift objects as much as 1,000 times their own weight using only water or air pressure. One 2.6 gram muscle is able to lift a 3 kilogram object, which is the same as a duck lifting a car.
NASA uses pressure-sensitive paint to test its rockets
How can NASA make sure its rockets are ready to handle the intense buffeting produced during launch? Scientists have recently started using pressure-sensitive paint (PSP) that reacts with oxygen to produce light. That way, scientists can actually visualize where the changing forces act on the rocket as it simulates acceleration during testing. The traditional method uses tiny microphones to measure buffeting, while this "unsteady" PSP is sprayed on in a thin layer, and contains pores so air can contact a greater surface area of the paint. Among other applications, it can be used to speed up and lower the cost of testing on projects like the Space Launch System.
The next iPhone's Force Touch reportedly trumps that on the Watch
Many expect the upcoming iPhone to include a pressure-sensitive screen, but just what will it entail? Will it be an upsized version of what you saw on the Apple Watch? Not by a long shot, if you ask 9to5Mac. Its sources claim that the future handset is using a next-generation version of Force Touch that recognizes three dimensions of input, not just the existing two. Reportedly nicknamed 3D Touch Display, it'll respond to multiple levels of pressure (a deeper press will trigger different functions, for instance) and allow app makers a whole new level of functionality. Just what Apple will do with this rumored feature is still up in the air, but you'll only have to wait a few days to get the full scoop.
Dark Sky uses your iPhone's sensors to improve weather forecasts
Your iPhone gives you weather forecasts right from the get-go, but it's now ready to shape those forecasts as well. Dark Sky has given its iOS app a big overhaul that, if you like, uses the barometer on your iPhone 6 or 6 Plus to contribute pressure readings. The hope is that these will dramatically improve short-term forecasts in the future -- you'll know that it's about to rain because iPhones nearby gave you a heads-up. There have been apps that crowdsourced pressure data before, but rarely with the intent to directly improve forecasts -- and not on the scale of Dark Sky, one of iOS' best-known weather tools.
BeBop's smart fabric puts sensors in everything you wear
Wearable sensors don't tend to do much; they're usually limited to health data like EKG readings or your heart rate. If BeBop Sensors has its way, though, they'll be useful for just about anything that comes in contact with your body. Its new smart fabric sensor tracks virtually every aspect of physical presence, including bending, location, movement and pressure. As you might imagine, that opens the door to... well, quite a lot. You could have smart insoles that track both your pace and your running style, or baseball gloves that help perfect your swing; BeBop also sees uses in everything from wearable controllers to smart yoga mats that improve your poses. The company is only providing the basic technology, not finished products, so it'll be a while before you see this smart cloth in something you can buy. Even so, it's clear that there's a lot of potential -- you may always have a way to measure your activities without resorting to wristbands or other conspicuous gear.
Processing trick turns off-the-shelf earphones into pulse rate monitors
We've seen earphones that double as health sensors, but they frequently require integrated (and sometimes bulky) equipment to get the job done. Bifrostec and the Kaiteki Institute have just solved that problem with processing technology that turns any pair of in-ears into a pulse wave sensor. The approach converts earphones into microphones that listen for eardrum movement, which is usually in sync with the pulse rate of a person's arteries. As the technique compensates for background noise, it lets users monitor their pulses while they listen to music -- and without having to wear head-mounted gadgets. While there's no word on when (or if) we'll see the pulse wave discovery reach shipping products, it's efficient enough that it could slip into conventional mobile devices almost unnoticed. Don't be surprised if a future smartphone can tell you when it's time to relax.
Nanowire sensor converts pressure into light, may lead to super-sensitive touch devices (updated)
Outside of pen input, pressure sensors don't get much love these days. However, Georgia Tech has just built an extremely accurate sensor that could give pressure-based devices their due. When a user pushes down on the new invention, its grid of zinc-oxide nanowires emits light that's captured by fiber optics underneath at a very sensitive 6,300DPI. The combination of high resolution with light-speed responsiveness could lead to touch surfaces that capture far more detail than we're used to. While computing interfaces are clearly prime candidates for the technology, Georgia Tech also sees potential uses in pressure-based fingerprint readers and even devices that simulate touch with skin-like behavior. We've reached out to the school for more information regarding its long-term plans, but it already anticipates improving the sensors with more efficient manufacturing techniques. Take a closer look at the sensor after the break. Update: We've since had a chance to follow up, and we're told that commercialization is likely five to seven years ahead.
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.
Indie Royale 'Hammerhead' bundle includes Richard & Alice, Primordia and more
The latest Indie Royale bundle is now available for the current minimum price of $5.68. The Hammerhead bundle includes Owl Cave's Richard & Alice, Primordia by Wormwood Studios, Pressure by Chasing Carrots, Forge by Dark Vale Games and Pandora Studios' Gas Guzzlers: Combat Carnage. The bundle seems immediately worthwhile to us just for the inclusion of Richard & Alice alone, per our recent review of the game. Those that pay at least $8 for the Hammerhead bundle will also receive MY OK BBS' chiptune album It's Not Great. There's also a mysterious sixth game in the bundle, likely to be revealed at a later time. The Indie Royale bundle is available on PC until June 7.
Surface Pro driver enables Pen pressure sensitivity in Adobe Photoshop
After a long and awkward delay, there's been some movement in the saga known as "Surface Pro's Pen accessory won't work with the software that could most benefit from it." Microsoft's Panos Panay tweeted yesterday that he had a beta driver from Wacom that had enabled his Pen's pressure sensitivity in Adobe Photoshop. Around the same time, an updated driver ("Enhanced Tablet Driver 7.1.1-12") appeared on Wacom's site, which PocketNow reckons contains the necessary fix. This file may not be final, and there's no specific reference to Microsoft's tablet in its changelog, but it's definitely worth a try at the source link below. Meanwhile, if you're one of the artistic types who's been holding off from buying a Surface Pro until this is resolved, then maybe just stay patient a little longer until more users report back on their progress. We're giving it a go ourselves, and in any case we've been assured by our own contacts at Microsoft that there'll be a happy ending within days.
Apple patent would have devices sense a squeeze through metal
Apple likes to build devices using metal. Unfortunately, the material isn't usually conducive to touch, in the literal sense of the word -- capacitive touch doesn't always register on a metal gadget, and you can often forget about a response to pressure. A newly published patent from the company could at last get these unfeeling devices to acknowledge our grip without putting sensors above the surface. Apple's method would detect the changes in capacitance between hidden nodes when a device's shell is put under strain, and trigger a hardware or software reaction when there's a strong-enough squeeze. The concept is simple enough. Just what Apple would like to do with the patent, if anything, is the real riddle. The patent was originally filed in 2009, and covers just about everything computer- or mobile-based that Apple could produce; any burning desire to use the technique would likely have been satisfied by now. If our future iPhones or Macs ever answer a hug with more than just cold indifference, though, we'll know why.
'Pressure' forces racing and vintage quack medicine together
Pressure, developed by Chasing Carrots and published by TopWare Interactive, is definitely the first action racing game we can think of that reminds us of the Kellogg family's Battle Creek Sanitarium.The steampunk racing/shooting game has players, driving a steam-powered buggy, attempting to defeat the "Earl of Wellness," who has drained the local lake to provide water for his "Wellness Spa Temple."Once again, this is a racing game. See for yourself above. It's coming to PC, PS3 download, and XBLA.%Gallery-168363%
Pressure-sensing PC technology knows when you're busy, blocks notifications accordingly
We know better than most that when you're working to a deadline, constant pop-ups, notifications and pings can be a real pain. Our frustrations might soon become a thing of the past, however, with some help from boffins at the Graduate University for Advanced Studies in Japan. They are working on technology which monitors keyboard pressure and silences those distractions until it deems you're not busy, showing over 80 percent accuracy during volunteer testing. Understanding that quiet time is also appreciated for other tasks, they plan to use similar techniques to spot when you're staring intently at that report or -- more importantly -- attending to a beverage. It's still early days for the project, but if the stress-saving tech ever spawns a product, we'll take two please. [Image Credit: Getty Images / Jean Louis Batt]
Alibaba claims Google leaned on Acer to cancel launch of CloudMobile with Aliyun in China
Just yesterday Acer was getting ready to unleash its CloudMobile smartphone on the Chinese public sporting an equally local (and equally not Android) Aliyun operating system. According to Reuters, however, when journalists turned up for the launch event today, an Alibaba (who make Aliyun) spokesperson told them the launch had been cancelled, before later releasing a statement saying Acer had received pressure from Google to pull the launch. The competing OS manufacturer claims that the Acer was told product collaborations and Android authorization would cease if the product was released. So far Google has declined to comment, but if true, represents some significant strong arming, in what is clearly a significant market. We have reached out to Google for comment ourselves. More as we know it.
STMicroelectronics details pressure sensor in your Galaxy S III, can tell when you're mountaineering
If you're the sort to tear down your Galaxy S III, you might have noticed a mysterious STMicroelectronics LSP331AP chip lurking on the motherboard. While we've known that it's a pressure sensor, we now know that it's a new generation -- new enough that ST is just getting to explaining the technology to a mainstream audience. The piezoresistor-equipped MEMS chip tracks altitude through atmospheric pressure with an uncanny knack for precision; it can tell when you've crossing between floors, which could be more than handy for future iterations of indoor navigation. Don't worry if you're an extreme sports junkie that might push the limits, either. The sensor can do its job at the kinds of pressure you'd normally see when 32,800 feet high or 5,900 feet below sea level, which should keep it working even if you're checking your phone during a climb up K2 or a HALO skydive. We don't know if anyone beyond Samsung is lined up to use ST's pressure sensor in their devices, but we wouldn't be surprised if it becomes a mainstay for smartphones and outdoor gear in the near future.
Netatmo Urban Weather Station tells iOS users when it's safe to brave the great outdoors (video)
We haven't seen weather stations garner the same level of clever mobile integration as other pieces of household gear -- like, say, thermostats. Netatmo wants its newly available Urban Weather Station to inject a similar dose of life into a category that some of us still associate with the thermometer by the window. The aluminum tube design certainly gives a fresh look to the WiFi-linked indoor and outdoor sensors, but the real trick is the matching iOS (and eventually Android) app. It's for more than just gauging the wisdom of biking to work: the free app tracks historical trends and shares them with fellow users in a network that Netatmo hopes will provide a better understanding of wider-scale and longer-term trends. The sensors go beyond just obvious air quality, humidity, pressure and temperature conditions as well, flagging noise levels and warning if the CO2 levels are high enough to warrant airing out the house. The $179 price for the Urban Weather Station isn't trivial, but neither is knowing just how well you can cope with your environment.
Insert Coin: PressurePen stylus lets you make all kinds of lines on your tablet
In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject line. If you're like Charles Mangin, you love your iPad or Android tablet, but wish it was a little more Wacom-esque. But why wait for hardware manufacturers to bring the styli to you? Mangin has concocted the PressurePen, a pressure-sensitive stylus that plugs into a tablet's audio jack. The peripheral sends a tone to the tablet based on how far the tip of the pen is pushed in. The tone affects the thickness of the pen stroke, helping you alternate the sizes of lines more naturally than on a standard tablet. Mangin is shooting for $10,000 over on his Kickstarter page, with a little under a week and around $4,000 left to go. Those who pledge $60 or more will get a PressurePen to call their own. Mangin will also be open sourcing the plans for the pen, so those with access to a 3D printer will be able to make their own shell at home. Video of a PressurePen prototype in action after the break.
City of Steam fashions a pressurized skill tree
Many MMOs have skill or talent trees, but when you're doing a steampunk game, why not take a bland staple of the genre and turn it into something awesome? That's what City of Steam's Lead Designer Dave Winking is promoting when he shows off the team's ideas for turning the mundane into the fantastical. After taking feedback from previous generic builds, City of Steam's dev team revamped the skill tree's visuals and mechanics to entice a "whoa!" out of its players. The concept is that the tree is now a maze of pipes, boilers, and valves. Players will build up "pressure" over time, pressure that can be vented into different pipes. The more pressure in a pipe, the higher a skill goes, and once a skill hits 100% pressure, it's usable by the player. Winking says that players have more options than just filling up a pipe; they can also over-pressurize pipes to achieve higher skill ranks and take multiple paths to achieve better skills. There's even a mystery skill that Winking says will "make your character explode into pieces of bread with cat's heads stuck through them." Of course, he then says he's probably teasing about the last thing.
Goodyear's self-inflating tires could improve gas mileage, leave Schrader valves unsatisfied
Reminiscent of Ghostbuster's Marshmallow Man, new Goodyear tires might just Stay-Puft on their own. The company is developing Air Maintenance Technology (AMT) tires with built-in pumps to keep themselves at the perfect pressure. The reason? Even slightly under-inflated tires can drop your mileage by 3.3 percent, costing you cash at the pump. For highway-hustling commercial trucks that's a whole lot of moola, leading the US Department of Energy's Office of Vehicle Technology to grant Goodyear $1.5 million towards self-plumping commercial tire development. For those of us who don't wear mesh hats, Goodyear is working on a consumer version in its Luxembourg lab. It's unclear exactly how they will work, but earlier implementations have a pipe that's compressed as the tire rolls, allowing air to enter the tire without bursting thanks to a pressure sensitive valve. With so much automated car technology now all we need is the kind that cleans out its own trunk and pumps its own gas. Check out the full PR after the break.
Scientists study orca ears, employ lasers to create hyper-sensitive underwater microphone
There are plenty of reasons to want to monitor what's going on in the ocean, from whale migration, to the recent stylistic resurgence of hot crustacean bands. There are certain inherent difficulties, however, in creating a powerful underwater microphone, namely all of that water you've got to contend with. A team of scientists has taken cues from the design of orca ears, in order to develop a powerful microphone that can work far beneath the waves. The researchers developed membranes 25 times thinner than plastic wrap, which fluctuate as sound is made. In order to operate at extreme depths, however, the microphone must fill with water to maintain a consistent pressure. So, how does one monitor the minute movements of a membrane hampered by the presence of water? Lasers, of course! The hydrophone can capture a 160-decibel range of sounds and operate at depths of 11,000 meters, where the pressure is around 1,100 times what we're used to on earth. So if the orcas themselves ever master the laser, at least we'll be able to hear them coming.
