We scan the digital environment to examine the leading trends in emerging technology today to know more about future.


We have added a few indices around the site. Though we look to the future, we need to keep an eye on the present as well:

Amputee Feels in Real-Time with Bionic Hand

EPFL writes:

Dennis Aabo Sørensen is the first amputee in the world to feel sensory rich information – in realtime – with a prosthetic hand wired to nerves in his upper arm. Sørensen could grasp objects intuitively and identify what he was touching while blindfolded.

The Open Hand Project

A 3D printed robotic prosthetic hand which is a fraction of the cost compared to current available models - video embedded below:

The Open Hand Project aims to make advanced prosthetic hands more accessible to amputees. The Dextrus hand is the realization of this goal, it’s a low-cost robotic hand that offers much of the functionality of a human hand. Ultimately, these hands will be sold for under $1000 (£630).

The Open Hand Project is open-source, which means all of the plans to make a robotic hand will be published online with no patents, anyone has the right to make their own and even sell it themselves. You’re funding the full development of the hand with the Open Hand Project, after that companies will be able to use the designs and sell the hands all over the world. This really helps get these devices out to developing countries and places where import taxes might otherwise increase the cost of distribution.

The project is looking for funding through an indiegogo campaign - more info can be found here

DIY bionics as a step towards fully integrated neural linked systems.

DIY bionics - making kids smile again.

See the joy in Liam’s eyes as he is grasping a ball with his right hand for the first time. By the time this cute fellow grows up, he will have a bionic hand that will be connected to his neural-system and be indistinguishable from his biological body; but all Liam cares about for now his being able to play ball.

Bionic App

via NewScientist:

The powered thumb is controlled by signals from the user’s arm muscles or - in a first for upper limb prostheses - via a smartphone app: a tap of the screen and the hand automatically arranges itself into a preset grip. The thumb can move into 24 different positions and new, extra-sensitive fingertip electrodes also give improved dexterity.

“Powered thumb rotation, combined with the mobile app and quick access to all these new grips, gives me natural hand function that I never imagined would be possible,” says Bertolt Meyer, who wears one of the new hands.

The app makes it easy to configure presets by group, such as “work”, which includes positions ready for typing, handling documents or using a mouse. The app also includes diagnostic tools and training modes for new users.

A quick update on the amazing bebionic prosthetic hand.

Advanced Prosthetic Hand Ties Shoes, Deals Cards

This hand, the bebionic3, actually shows it doing some of the stuff you’d think it might: tying shoes, dealing cards, picking up household items, etc.

Those tasks make it sound mundane, but it’s actually a pretty darn impressive hand. Not only can it squeeze and pinch, it can also do some less commonly used movements, like making the rock-on devil horns or spinning in a full circle. It even automatically grips an object when it detects that the object’s slipping.

New Prosthetic Hand Has Sweet Skills, Terminator Looks


Nigel Ackland lost half his arm in an accident six years ago. But now he’s got a carbon-fiber prosthetic arm that is strong enough to grip a beer yet gentle enough to clutch an egg.

The prosthesis is called the BeBionic3 myoelectric hand and is made by a British company named RSLSteeper. It’s made from a carbon-fiber body, making it light yet strong, and has aluminum and alloy knuckles. The hand can do much more than the typical prosthesis.

“A standard prosthetic hand has one pinch, where the thumb and fingers come down together,” said Richard Shapcott, general manager of SteeperUSA, the US branch of RSLSteeper. This can produce a strong grip that can’t handle more delicate tasks.

The BeBionic3 hand, in contrast, has different motors for each finger, allowing them to articulate separately to get a combination of strength and grip. Inside the prosthesis is a small amp that picks up the minute myoelectric signal produced by human muscles. The signal is then amplified and tells the hand whether to open or close. When Ackland tenses the outer muscle on his arm, the hand will open. If he tenses the other, it will close. Tensing both muscles together switches between controlling the hand and spinning the wrist. Because the strength of the user firing their muscles determines the strength of the grip, someone outfitted with the device can gently clutch a egg, grasp a tool, or shake a hand.

The BeBionic3 comes with eight different grips programmed into it, which can be augmented with software that comes with the product. In the video above, you can see Ackland demonstrating some of the grips, which include extending his pointer finger, gripping something with all fingers, and making a come-hither motion. “This is the one that scares children and upsets my wife,” said Ackland in the video.

The thumb can be moved into opposition for additional grip types. Ackland switches between the different modes by firing his muscle twice in close succession. The arm has a small learning curve but Ackland has been wearing it for several months and appears well versed in its abilities in the video above.

Shapcott says that between 30 and 50 people have been outfitted with the device since September. Though it would retail for a large price, which he did not disclose, he said that the hand is covered by most insurance and Medicare in the U.S. and the national healthcare in the U.K.

Users can customize the device to a certain extent, adding new modes or changing the order in which they appear. RSLSteeper also makes a silicon cosmetic skin that mimics human flesh to cover the arm but it looks like Ackland is happy to leave it exposed as a futuristic Terminator device.

Future versions will likely have more modes and more capabilities, said Shapcott. But the human hand is still far more complex.

“Just bringing your pinky to your thumb is nearly impossible to do with motors,” he said. “Unless you’re doing something animatronic, but then that couldn’t stand up to the rigors of daily life.”
