ICYMI: A prosthetic hand with two senses
Today on In Case You Missed It: We get our first close-up look at Saturn's rings thanks to the Cassini spacecraft -- which just completed the first of its twenty-two passes through the planets' famed hoops. NASA stitched together the images from the craft to give us Earthlings an incredible first-person (first-spacecraft?) point-of-view of the recent dive, which began at the north pole of the planet and moved down its side. The imaging team working on Cassini's trips expects to get even better data from the subsequent trips, which will gather information on Saturn's gravity and magnetic fields.
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.
Prosthetic hand restores a man's sense of touch
DARPA promised prosthetic limbs that produce realistic sensations, and it's making good on its word. The agency's researchers have successfully tested an artificial hand that gave a man a "near-natural" level of touch. The patient could tell when scientists were pressing against specific fingers, even when they tried to 'trick' the man by touching two digits at once. The key was to augment the thought-controlled hand with a set of pressure-sensitive torque motors wired directly to the brain -- any time the hand touched something, it sent electrical signals that felt much like flesh-and-bone contact.
Touch Bionics' latest 'i-limb' offers a powered rotating thumb, smartphone controls
Touch Bionics' i-limb prosthetic hand has advanced quite a bit in recent years, adding features like Bluetooth connectivity and upgraded fingers. Now the company has made available its latest revision, the i-limb ultra revolution, which offers powered thumb rotation for some added dexterity, as well as a new "biosim" app (iOS-only for now) that gives the wearer quick access to 24 different grip patterns in addition to diagnostic and training modes. Of course, the hand isn't only controlled using a phone; as with previous models, it relies on muscle signals to shift into different pre-set patterns, which let the wearer perform a wide variety of actions. You can get a glimpse of some of those capabilities in the video after the break.
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.
Virtu-LIMB lets prospective patients take upgraded Touch Bionics hand for a spin
It looks like Touch Bionics is bringing the classic "try before you buy" racket to the world of bionic hands. Say hello to the Virtu-LIMB, a simulation and training setup for myoelectric upper limb prostheses. This little yellow dome tethers to a patient's arm and transmits their myoelectric signals to a nearby computer via Bluetooth -- the data is then used to either control an i-LIMB Ultra prosthetic hand or, failing that, a PC simulation of one. The rig was shown at the American Orthotic & Prosthetic Association National Assembly this week, and can be used to help clinicians fine-tune prostheses for their patients, train patients to manipulate their bionic digits, or even demonstrate the Touch Bionics' i-LIMB to a potential user. The i-LIMB Ultra itself is an upgraded replacement for the outfit's i-LIMB Pulse, featuring a new variable digit-by-digit grip mode, increased flexibility, extended battery life (and low battery audio warning), and the ability to create custom gestures. The new unit even returns to a natural resting state after a period of inactivity, keeping the devil out of your idle hands.
ITK's Handroid: a softer, gentler robotic hand (video)
Most robotic hands are built with a series of individual motors in each joint, making them heavy, expensive and prone to gripping everything with the subtlety of a vice. Japan's ITK thinks it's solved those problems with Handroid -- designed with cords that mimic the muscles in our meat-paws. No motors mean it's far lighter than the standard Terminator design, and it's controlled with a glove that allows it to mirror the operator's movement as it happens. ITK wants to sell Handroid for the bargain price of $6,500 by 2013 for use in environments too dangerous for humans, but because it's so light and cheap it could also see use as a medical prosthesis. You can see how the device works in the video after the break.
New prosthesis sends feedback to the brain, might alleviate phantom pain
Even as prosthetic technology advances, the problem of phantom limb sensation persists. Essentially pain, pressure, or some other stimulus attributed by the brain to a limb that has been lost, the exact cause for this is unknown -- and it's a very real problem for amputees. Hoping to better understand (and someday maybe eliminate) the phenomenon, researchers at the University of Jena in Germany have developed a prosthesis that uses sensors and a stimulation unit to send feedback from the patient's artificial hand back to the brain, offering some relief to the individual in the process. So far, the team has had some success, but as the school's Dr. Thomas Weiss points out, there is quite a bit of work yet to be done to determine if "the hand is helpful to only a few people or if it is a therapeutic for all wearers of artificial limbs."
Touch Bionics i-LIMB Pulse, the Bluetooth bionic hand, makes your meaty one obsolete
Let's say you got in a fight with your dad. You said some things, he said some things, and then he cut your hand off. Don't go all emo: Touch Bionics has a new product that will have you overthrowing empires again in no time. A successor to the company's revolutionary i-LIMB Hand, the i-LIMB Pulse is a more streamlined version meant to look more natural, also offered in two sizes, and comes complete with Bluetooth that allows prosthetists and users to tweak settings easily. The device's name comes from its "pulsing technology" that boosts strength, enabling it to handle up to 90kg (about 200lbs), which is a lot more than our crippled carpal tunnels can manage these days. The Pulse starts shipping to would-be chosen ones on June 1 -- just in time for Father's Day. %Gallery-92450%
Prosthetic, robotic 'Smart Hand' has feelings, too
Researchers in Italy and Sweden have spent the last ten years developing what they call the "Smart Hand," a prosthetic hand which enables feeling in its fingertips. The hand -- which was recently wired up to a test patient through a surgical procedure -- has four motors and forty sensors which are linked directly to the brain. In the surgery, the nerve endings of the patient were linked up to receptors in the hand, which allows for feeling in the fingertips of the hand, even though the hand is not really a part of his body. In the video after the break, you can see the greater precision and dexterity this hand allows for. Though the research still needs to be refined before practical use, it looks pretty far along -- and pretty awesome -- to us.
Aiko gets a new, Starbucks-ready hand prototype
Apparently that sexual harassment suit had a big payoff for Aiko: she's getting a hand. The developers of the fembot have created a hand for her botness, with five movable fingers, 15 movable joints, feedback sensitivity, low power consumption and palatable material cost of $1800. Oddly enough, the appropriate testing grounds for such a hand is Aiko's local neighborhood Starbucks, where she apparently regularly is required to grab straws, cups and cardboard sleeves for coffee she can't drink. How cruel. On the bright side, this hand isn't just for Aiko: it can also be attached to an amputee's forearm muscles, allowing for particularly low cost replacement hand -- though we're guessing it's going to need a bit more work before it's ready for mass human consumption. Video is after the break.
