Dust-sized wireless sensors could control prosthetics someday
See that minuscule component in the image above? That's a wireless sensor, and someday, doctors could slip it into our bodies to monitor our organs like a microscopic Fitbit or even to give quadri- and paraplegics the power to control robotic arms or legs. A team of scientists from the University of California, Berkeley have developed an early iteration of the sensor that's about the size of a grain of rice. Each sensor has a piezoelectric crystal that can convert ultrasound vibrations into energy. It also allows the teensy device to beam back data collected from nerve cells in the brain if it's used to control bionic limbs.
Prosthetic arms inspired by 'Deus Ex' are coming next year
Remember that prosthetic arm, inspired by Metal Gear Solid, that Konami developed for a British amputee? Well, it seems the company has started a trend. Square Enix and Eidos-Montréal have now teamed up with Open Bionics, a specialist in low-cost prosthetics, to develop some designs based on the world of Deus Ex. The franchise delves deep into a possible future where human augmentation is commonplace, changing society and warfare in equal measure. Two arms -- one based on Adam Jensen, the hero of Mankind Divided, another on the wider Deus Ex universe -- will be released next year as royalty-free designs that anyone can use.

Stanford researchers make artificial skin that senses touch
A team from Stanford University might have made a breakthrough that could change the lives of people with missing limbs. Researchers have developed an artificial substitute for skin that is capable of sensing when it is being touched and sending that data to the nervous system. It's hoped that technology like this could be used to build futuristic prostheses that could be wired into the nervous systems of amputees. In addition, not only will these people be able to know if they're touching something, they'll also know how much pressure is being used.
Young amputees will soon get 'Iron Man' and 'Star Wars' bionic hands
A heroic set of prosthetic hand designs will soon allow young amputees to transform into their favorite Disney characters. Whether they prefer a red Iron Man gauntlet, one of Queen Elsa's sparkling blue gloves or a hand inspired by Star Wars' iconic lightsabers, they'll be able to take on the world with a prosthetic that finally marries form and function. The three models have been created by Open Bionics, a startup working on cheap, 3D-printed hands for amputees. Joel Gibbard, the company's founder, says they'll cost around $500 and be available in 2016. Another, non-Disneyfied design should be roughly £2,000 ($3,071) -- considerably more, but still a fraction of what many existing prosthetics cost.
Gripping objects takes much more brain power than we thought
Researchers from Brown University have made a discovery about how the human brain operates when gripping an object. Previously, it's been assumed that the mind had a short, single command to drive the hand, but in reality it's much more complex than that. With this new information, it's hoped that engineers will be able to build prosthetic limbs that are significantly more responsive. In addition, the finds could also go some way to helping develop new tools for people with severe paralysis.
Prosthetic foot only needs 'mind control' for movement
During a press conference in Copenhagen on Wednesday, prosthetics manufacturer Ossur announced the release of an implantable sensor that allows users to mentally control a mechanical limb. The technology, known as an Implanted MyoElectric Sensor (IMES) will allow users to move the company's motorized Proprio Foot just like they do the real thing.
Prosthetic electrodes will return amputees' sense of touch
For all the functionality and freedom that modern prosthetics provide, they still cannot give their users a sense of what they're touching. That may soon change thanks to an innovative electrode capable of connecting a prosthetic arm's robotic sense of touch to the human nervous system that it's attached to. The device is part of a three year, $1.9 billion DARPA project and is being developed by Daniel Moran and his team at Washington University in St. Louis. The electrode, technically called a macro-sieve peripheral nerve interface, is comprised of a thin contact lens-like material less than 20 percent the diameter of a dime. It reportedly allows its users to feel heat, cold and pressure by stimulating the ulnar and median nerves of the upper arm.
Japanese bankers get exosuits to help move stacks of cash
Japan's Sumitomo Mitsui Banking Corporation announced Friday that it will provide Hybrid Assistive Limb (HAL) exosuits to select senior employees as part of a pilot program aimed at reducing the strain of moving currency. "There have been many cases when a physical burden was placed on senior employees carrying heavy parcels of banknotes and coins. By adopting Cyberdyne's robotic suits, we can help reduce that burden," Tomoyuki Narita, a spokesman at SMBC, told the Wall Street Journal. About 16 percent of Sumitomo's employees (and 25 percent of the nation) are over the age of 65. The HAL is designed to augment its user's strength, reducing the perceived weight of an item by 40 percent so that a 10-pound weight only "feels" like it weighs 6 pounds. Should the pilot program prove effective, Sumitomo could expand it to more branches throughout Japan. [Image credit: Sumitomo Mitsui Banking Corp]
'Thinking cap' controls prosthetic arm with thoughts, not surgery
The ability to control prosthetics with only the power of your mind has been around for a while, but it typically requires control electronics implanted directly into the patient. With this new, non-invasive method developed at the University of Houston, however, amputees can command their robotic limbs without surgery. Instead of implants, the UH system uses a wearable "thinking cap" (aka an EEG) that monitors brain activity externally through the scalp. A brain-machine interface (BMI) then interprets these brain waves and converts that intention into mechanical motion. Basically, the patient thinks about picking up an object, the BMI recognizes the intention and then tells an attached prosthetic to do so. Even at this early stage of development, University of Houston researchers have gotten the system to work properly 80 percent of the time.
Mind-controlled drones promise a future of hands-free flying
There have been tentative steps into thought-controlled drones in the past, but Tekever and a team of European researchers just kicked things up a notch. They've successfully tested Brainflight, a project that uses your mental activity (detected through a cap) to pilot an unmanned aircraft. You have to learn how to fly on your own, but it doesn't take long before you're merely thinking about where you want to go. And don't worry about crashing because of distractions or mental trauma, like seizures -- there are "algorithms" to prevent the worst from happening.
Derby the dog got 3D-printed paw prosthethics, now watch him run
Derby was born with deformations in both of his front legs, making movement and any kind of speed difficult, if not impossible. Now, he can run. The husky mix was fitted out with two prosthetics, custom-made on 3D sculpting software to fit his forearms. With some help from 3D Systems and several iterations later, and the curved prosthetics you see above became the final build. "The great thing about using 3D technology in Derby's case, is having these images on file on a computer, and being able to print them. [It] is a lot quicker than having to hand sculpt every single mold and rebuild these braces five to ten times," explained Kevin Atkins, 3D Systems' Freeform Product Manager. The team settled on these curved designs because there was the fear that more pointed iterations (like running blades seen on humans) would get caught in softer ground.
Goat-inspired prosthetic leg will give rock climbers better footing
For all the neural-controlled, bluetooth-enabled and sport-specific prosthetics humanity has designed over the years, one thing remains constant: most of of them are lousy for climbing rock faces. Design student Kai Lin learned this while researching artificial limbs in a prosthetic-design class at Pratt Institute -- traditional leg prosthetics don't have enough grip or articulation to facilitate effective climbing. Lin's solution to the problem is almost elegant in its simplicity. He designed a prosthetic leg inspired by one of nature's best rock climbers: the mountain goat.
'Cyberathlon' will see disabled athletes compete in powered exoskeleton races
Massive sporting events like the Olympics are becoming increasingly tech-charged, but the games themselves remain unchanged for the most part. A new event called Cybathlon, however, wishes to fully integrate technology into its events, for what's billed as "The Championship for Robot-Assisted Parathletes." Due to be held in Switzerland in 2016, races will feature "pilots" outfitted with powered limb prosthetics, exoskeletons and wheelchairs that can be either commercial products or research prototypes. There will also be a bike race for competitors with muscle stimulation devices, and a fully computerized event pitting brain-controlled avatars against each other on a virtual track. While there'll be medals and glory for some, it's hoped Cybathlon will raise awareness of assistive tech and encourage development in the area. Nothing like a bit of healthy competition to moisten an engineer's brow.
Handie prosthetic uses 3D printing and smartphones for much cheaper bionic hands (video)
The main aim of Handie, already a James Dyson award nominee, was to develop an artificial hand that offered a large degree of functionality without the brutal prices associated with prosthetics. With the latest model, it apparently skirts below a $400 price tag, substituting a smartphone for previously dedicated processing hardware as well as 3D printing. The use of printable parts makes Handie repairable, meaning it should last as long (or possibly longer) as models that use substantially more expensive materials. Because all the components (aside from the motors) can be printed, it means customization, design improvements and repairs are all possible -- and cheaply too. The team also has a customized mechanism for finger flexing, reducing the number of motors needed to just one per three-segment digit. These single motors are still able to passively change direction of fingers depending on the shape of an object. The heavy thinking is all assigned to a companion app on a nearby smartphone, which cuts the costs once again. The prosthetic makers demonstrated the Handie's capabilities at an early press event for this weekend's Maker Faire Tokyo. After working on prosthetics in college, development has focused on the fact that high functionality might not be the biggest priority, especially for users that may require two hand replacements, bringing us back to Handie's simple aim: "sufficient functions at an affordable price." Compare and contrast the rougher fresh-from-the-3D-printer model against a glossier Portal-ish version in our gallery below, and check out the full video explanation after the break.
iPhone app used to control Touch Bionics prosthetic hand
In 2008, Jason Koger had both of his hands amputated after accidentally coming into contact with a downed power line on his grandfather's farm. Since the accident, Koger has been using a variety of prosthetic arms to cope with everyday life. However, the prosthetics Koger has been using have been limited. In an interview with CNN, Koger said, "It's like I'm carrying a toolbox, but only have one tool. You can't use a wrench for everything." Now Koger has had the opportunity to be the world's first double-amputee to use some remarkable technology: the i-limb ultra revolution. Designed by Touch Bionics in the UK, the i-limb offers the most advanced and versatile prosthesis available, with a powered rotating thumb. It also includes biosim, an iPhone app that gives Koger instant access to 24 Quick Grip patterns. The biosim app lets Koger choose from a selection of automated grips and gestures which aid in daily tasks, like index point for typing on a keyboard or a touch screen, precision pinch mode for gripping small objects, and a natural hand position. The app also lets Koger personally customize his own grips and gestures. Using the Touch Bionics prosthetics and app, Koger said, "Nothing is perfect, but I feel like I can be a more active participant in everyday life with these hands. I can do pretty much everything I could before; it just might take me a little longer." Read the full interview and watch a video of the prosthetics and app in action at CNN Health. [Via Gizmodo]
AMP-Foot 2.0 prosthesis gives the power of real feet, keeps a light step (video)
It was five years ago that prosthetics took a very literal step forward when Arizona State University's SPARKy foot offered a more natural walk, capturing the inherent kinetic energy that previously needed a big motor to replicate. Belgium's Vrije Universiteit Brussel may well carry the torch for the next wave of artificial limbs. Its second-generation Ankle Mimicking Prosthetic Foot (AMP-Foot 2.0) uses a pair of force sensors to determine the leg's relative position and let an actuator build energy when the foot bends, locking the power away to use only when the owner pushes off. The efficiency produces all the torque needed to let a 165-pound person walk, but with just a 30W to 60W motor versus SPARKy's 150W -- a big help to battery life that also reduces the AMP-Foot 2.0's weight to that of the fleshy kind. We don't know how likely it is the Belgian prosthesis goes beyond the prototype phase; if we had our way, it would move just as quickly as future wearers undoubtedly will.
Touch Bionics releases new prosthetic fingers, flips the old ones the bird
The only upgrades available for our puny human hands are gaming controller calluses, but if you're sporting an i-LIMB digits hand prosthesis, you can now grab a set of improved fingers. Touch Bionics' "smaller, lighter and more anatomically accurate" appendages are now available worldwide, as well as a new wrist-band unit which houses all the necessary computing power and juice for their function. Best of all, these developments allow more people to adopt the tech than the previous generation, including those with more petite hands or finger amputations closer to the knuckle. We don't know how much it'll cost for a fresh set, but we'll let health agencies and insurance companies deal with that part. With these upgrades and RSL Steeper's latest offering, it won't be long before our flesh-based variants are meager in comparison.
New beBionic hand almost doubles its grip-strength, steered by user's electrical 'skin signals'
RSL Steeper's beBionic3 still packs the same wireless chip, customizable silicone overlays and speed controls of its predecessor, but is now stronger and more durable. It's been redesigned with an aluminum chassis and new thumb and can now handle up to 99 pounds of weight, with almost double the grip-strength of its predecessor. The bionic hand traces faint electrical signals across the user's arm skin, amplifying them to the five digits, which can contort into 14 different grips. The mouse configuration, demonstrated in the video below, lets the user operate both buttons while holding onto the peripheral. The hand will cost between $25,000 and $35,000, depending on both the hardware and software configurations. See how the third-generation bionic limb grabs blocks, ties shoe-laces and wields pens after the break.
3D printed 'Magic Arms' give a little girl use of her limbs
Don't get us wrong, we adore 3D printers and the whole additive manufacturing movement. But, if all you're going to get out of the ABS-jets are some companion cubes and a raptor claw, well then, we don't think there's much hope for the technology. Thankfully there are people out there (much better people than us, we might add), who have turned to 3D printers to actually improve peoples lives. Take, for example, the tale of two-year-old Emma, born with the congenital disorder arthrogryposis multiplex congenita (AMC). The disease causes a person's joints to become locked in a single position, in Emma's case, it was her arms. There are prosthetics that can help, but most are made of metal -- including the anchor vest -- which would make them too heavy for a 25-pound girl. Instead of going off the shelf, doctors turned to a 3D printer from Stratasys to create custom molded parts and a lightweight vest for Emma. The result: the two-year-old who once could not lift her arms is now able to play, color and feed herself. Printing the parts also solves another major issue -- Emma is growing... quickly. The adorable tot has already outgrown her first vest, but her mother just calls the Nemours/Alfred I. duPont Hospital for Children and has a new one made. The same goes for replacement parts. Should a hinge or brace break, it need only be a matter of hours (not days or weeks) before a new one is delivered. For more details check out the heartwarming video after the break.
