Unlike traditional devices, the artificial hand can be customised for children and youths, who otherwise require an expensive series of resized models as they grow up.
The company Cure Bionics also has plans to develop a video game-like virtual reality system that helps youngsters learn how to use the artificial hand through physical therapy.
Mohamed Dhaouafi, the 28-year-old founder and CEO of Cure Bionics, designed his first prototype while still an engineering student in his home city Sousse.
“One team member had a cousin who was born without a hand and whose parents couldn’t afford a prosthesis, especially as she was still growing up,” he said.
“So we decided to design a hand.”
Dhaouafi launched his start-up in 2017 from his parents’ home, at a time when many of his classmates chose to move abroad seeking higher salaries and international experience.
“It was like positive revenge,” he told AFP. “I wanted to prove I could do it. I also want to leave a legacy, to change people’s lives.”
Dhaouafi pointed to hurdles in Tunisia, where it can be hard or impossible to order parts via large online sales sites. There is a lack of funding and, he said, “we lack visionaries within the state”.
But by pooling money raised through sponsored competitions and seed investment from a US company, he was able to recruit four young engineers.
They are now fine-tuning designs, writing code and testing the artificial hand.
‘Climb like Spiderman’
The device works with sensors attached to the arm that detect muscle movement, and AI-assisted software that interprets them to transmit instructions to the digits.
The hand itself has a wrist that can turn sideways, a mechanical thumb and fingers that bend at the joints in response to the electronic impulses.
To teach youngsters how to use them, Cure has been working on a virtual-reality headset that “gamifies” the physical therapy process.
“Currently, for rehabilitation, children are asked to pretend to open a jar, for example, with the hand they no longer have,” said Dhaouafi.
“It takes time to succeed in activating the muscles this way. It’s not intuitive, and it’s very boring.”
In Cure’s version, the engineer said: “We get them to climb up buildings like Spiderman, with a game score to motivate them, and the doctor can follow up online from a distance”.
3-D printing meanwhile makes it possible to personalise the prosthesis like a fashion accessory or “a superhero’s outfit”, said Dhaouafi.
Cure hopes to market its first bionic hands within a few months, first in Tunisia and then elsewhere in Africa, where more than three-quarters of people in need have no access to them, according to the World Health Organization.
“The aim is to be accessible financially but also geographically,” said Dhaouafi.
The envisaged price of around $2,000 to $3,000 is substantial, but a fraction of the cost of bionic prostheses currently imported from Europe.
Cure also aims to manufacture as close as possible to the end users, with local technicians measuring the patients and then printing individually fitted devices.
“An imported prosthesis today means weeks or even months of waiting when you buy it, and again with each repair,” the inventor said.
The bionic hand is made of Lego-like parts that can be replaced if damaged or to match a child’s physical growth.
It can also be solar-powered via a photovoltaic charger for use in regions without a reliable electricity supply.
The 3-D printing of rudimentary prostheses started about a decade ago and is becoming standard.
It is not a magic solution because specialised medical know-how is still crucial, said Jerry Evans, who heads Nia Technologies, a Canadian non-commercial organisation that helps African hospitals manufacture 3-D-printed lower limbs.
“3-D printing is still in its early stages,” he said, “but it is a major game changer in the field of prosthetics and orthotics.”
“Developing countries will probably leapfrog to these technologies because the cost is much lower.”
Sam Stranks, University of Cambridge describes “How a new solar and lighting technology could propel a renewable energy transformation”. This will undeniably come to some help those countries that have opted strongly for renewables, such as Tunisia.
The demand for cheaper, greener electricity means that the energy landscape is changing faster than at any other point in history. This is particularly true of solar-powered electricity and battery storage. The cost of both has dropped at unprecedented rates over the past decade and energy efficient technologies such as LED lighting have also expanded.
Access to cheap and ubiquitous solar power and storage will transform the way we produce and use power, allowing electrification of the transport sector. There is potential for new chemical-based economies in which we store renewable energy as fuels, and support new devices making up an “internet of things”.
But our current energy technologies won’t lead us to this future: we will soon hit efficiency and cost limits. The potential for future reductions in the cost of electricity from silicon solar, for example, is limited. The manufacture of each panel demands a fair amount of energy and factories are expensive to build. And although the cost of production can be squeezed a little further, the costs of a solar installation are now dominated by the extras – installation, wiring, the electronics and so on.
This means that current solar power systems are unlikely to meet the required fraction of our 30 TeraWatt (TW) global power requirements (they produce less than 1 TW today) fast enough to address issues such as climate change.
Likewise, our current LED lighting and display technologies are too expensive and not of good enough colour quality to realistically replace traditional lighting in a short enough time frame. This is a problem, as lighting currently accounts for 5% of the world’s carbon emissions. New technologies are needed to fill this gap, and quickly.
Our lab in Cambridge, England, is working with a promising new family of materials known as halide perovskites. They are semiconductors, conducting charges when stimulated with light. Perovskite inks are deposited onto glass or plastic to make extremely thin films – around one hundredth of the width of a human hair – made up of metal, halide and organic ions. When sandwiched between electrode contacts, these films make solar cell or LED devices.
Amazingly, the colour of light they absorb or emit can be changed simply by tweaking their chemical structure. By changing the way we grow them, we can tailor them to be more suitable for absorbing light (for a solar panel) or emitting light (for an LED). This allows us to make different colour solar cells and LEDs emitting light from the ultra-violet, right through to the visible and near-infrared.
Despite their cheap and versatile processing, these materials have been shown to be remarkably efficient as both solar cells and light emitters. Perovskite solar cells hit 25.2% efficiency in 2019, hot on the heels of crystalline silicon cells at 26.7%, and perovskite LEDs are already approaching off-the-shelf organic light-emitting diode (OLED) performances.
Unlike conventional silicon cells, which need to be very uniform for high efficiency, perovskite films are comprised of mosaic “grains” of highly variable size (from nano-meters to millimeters) and chemistry – and yet they perform nearly as well as the best silicon cells today. What’s more, small blemishes or defects in perovskite films do not lead to significant power losses. Such defects would be catastrophic for a silicon panel or a commercial LED.
Although we are still trying to understand this, these materials are forcing the community to rewrite the textbook for what we consider as an ideal semiconductor: they can have very good optical and electronic properties in spite of – or perhaps even because of – disorder.
We could hypothetically use these materials to make “designer” coloured solar cells that blend in to buildings or houses, or solar windows that look like tinted glass yet generate power.
But the real opportunity is to develop highly efficient cells beyond the efficiency of silicon cells. For example, we can layer two different coloured perovskite films together in a “tandem” solar cell. Each layer would harvest different regions of the solar spectrum, increasing the overall efficiency of the cell.
Another example is what Oxford PV are pioneering: adding a perovskite layer on top of a standard silicon cell, boosting the efficiency of the existing technology without significant additional cost. These tandem layering approaches could quickly create a boost in efficiency of solar panels beyond 30%, which would reduce both the panel and system costs while also reducing their energy footprint.
These perovskite layers are also being developed to manufacture flexible solar panels that can be processed to roll like newsprint, further reducing costs. Lightweight, high-power solar also opens up possibilities for powering electric vehicles and communication satellites.
For LEDs, perovskites can achieve fantastic colour quality which could lead to advanced flexible display technologies. Perovskites could also give cheaper, higher quality white lighting than today’s commercial LEDs, with the “colour temperature” of a globe able to be manufactured to give cool or warm white light or any desired shade in between. They are also generating excitement as building blocks for future quantum computers, as well as X-Ray detectors for extremely low dose medical and security imaging.
Although the first products are already emerging, there are still challenges. One key issue is demonstrating long-term stability. But the research is promising, and once these are resolved, halide perovskites could truly propel the transformation of our energy production and consumption.

What Can One Person Do to Protect The Environment?
Three things: Innovate, call their Representative, and organize boycotts
Every time I went to a big-chain coffee store I made sure to pointedly ask for my coffee “for here, in a mug” while making eye contact with the cashier and miming holding a mug. Even with all this emphasis, about every one time in twenty I got handed a disposable coffee cup. At this point I’d be torn: that cup is going in the trash no matter what I did; but I dislike the experience of drinking from a disposable coffee cup. I usually ended up asking the barista to pour it into a mug for me.
Eventually, I told my regular barista that I’d quit disposable coffee cups as a new year’s resolution (which it was not). He changed the order and thanked me for making that resolution.
Most people reacted similarly when I told them what I was doing: with admiration, and then backing away by saying they could never do it themselves. Overall, not an encouraging reaction, because I’m not having much impact by myself. I’m just one person out of billions.
Innovate in your household.
My zero-waste experiment in 2019 resulted in a lot of frustration, but that frustration was useful. I deeply understood the difficulties of eschewing disposable cups.
Using this knowledge, I’ve been experimenting with methods to store my reusable cups and workflows for washing and replacing them. I’m hoping to find or develop a cup that’s fun to drink out of, easy to wash, store, and keep dry.
Innovations like this aren’t particularly high-tech or difficult to do, but that is how progress often happens. According to Eric Von Hippel, a professor who studies innovation at MIT,
Every field we look at in terms of the basic innovations, about half were done by users. And it’s fantastic. Companies very seldom mention the user-developed roots of their innovations.
If you’re frustrated by a problem, you’re uniquely qualified to figure out a solution, whether that’s a trash sorting system, a modified water bottle, or durable clothing.
People modifying products to make them do what they want is how we got the mountain bike. Companies often incorporate the modifications users want, as Von Hippel describes.
And then as a lot of people begin to do it, they say, “Aha! Not only is there a proven innovation, but there’s a signal of general demand.” And that’s the point at which you begin to define what a mountain bike should look like.
Participate in the political process.
Innovating helps create the technologies and processes that push the envelope beyond what we already have. Now the question is, will people use them?
They will if you regulate industries and compel them to adapt with the improvements in the state of the art.
Politics is an area where at first glance, it can seem like an individual voter has no influence. I found the idea of getting involved overwhelming. The 2018 election was the first time I participated beyond voting — I canvassed voters, phone banked, and called my Representatives, as often as I felt up to it, and eased my way into greater engagement.
And the results showed me how momentum can build.
Start small. Sign up for a mailing list of an organization like the Sierra Club, League of Conservation Voters, or any group that resonates with you, and keep aware of environment-related bills that are coming up in your state or country.
Then, after a while, when you feel brave enough, call your Member of Congress or whoever represents you win your government, and tell them how you’d like them to vote on it.
I put this last because this is where most people assume you have to start. I am in favor of boycotts, but only when there is enough leverage to give them a chance of success.
Boycotts tend to work by tarnishing a company’s brand. They work best when the company has a good reputation that is sliding, and that it wants to restore. Boycotts don’t need to significantly impact the company’s revenue to succeed.
Most importantly, they need to be well-organized, focused, and strategic. So just buying what you approve of and not buying what you don’t will not have much of an impact.
[…] we have somehow inculcated a belief that if someone fails to boycott a company, she lacks standing to object to political behavior or to petition Congress for change. People feel guilty about not boycotting, and that guilt gets in the way of full-throated political protest.
There’s no need to feel guilty about the products you buy. You can’t boycott every flawed product in the world at once; you wouldn’t be able to live.
It’s a good idea to learn to plan an effective boycott. It starts with choosing the right target — a company that is sensitive to criticism. Done right, boycotts can succeed.
My avoidance of disposable coffee cups probably didn’t cause the coffee shop to order fewer of them. It probably didn’t cause the overall market for disposable cups to decrease, or fewer cups to be manufactured.
That’s okay because my experiment got me thinking bigger — about the possible products we haven’t yet invented, the legislation we need, and the markets and industries as a whole.
It got me thinking about where we have the most leverage. That’s where we are going to act.
Not that long ago, people like Abdullah, a young Syrian man who was forced by the ongoing war to drop out of university, would have found it nearly impossible to safely earn a living. But through Edraak, an Arabic platform for open online education launched by the Queen Rania Foundation in Jordan, he gained graphic design and digital marketing skills. Now, he earns a decent living as a freelance remote worker in Jordan.
Amid the dual economic shocks of the COVID-19 pandemic and the collapse in oil prices, digital platforms are becoming even more critical to the region’s economy. With schools being closed since March and 4 in 5 workers affected by business closures globally, per International Labor Organization estimates, the shut-down of public life has revved up the need to move to digital, virtual, and remote learning solutions to build skills and ensure opportunities for people to earn a living.
Yet this emergency need is not being met. Moreover, MENA is missing real-time opportunities for digital development. Digital transformation can lead to rapid, sustained growth, but only if countries invest in digital infrastructure and human capital.
The key to success in this changing landscape is a digital skills revolution. While definitions and typologies differ, ‘digital skills’ generally refers to students, workers and people of all ages having and applying competencies, knowledge and attitudes to learn, earn and thrive in digital societies.
Digital skills most commonly comprise a continuum of basic, intermediate or advanced skills; and, as we will discuss in our next blog on competencies, they may alsorefer to a range of different abilities, many of which are not only ‘skills’ per se, but a combination of behaviors, expertise, know-how, work habits, character traits, dispositions and critical understandings.
As laid out by the International Telecommunication Union, Basic Skills are the general ICT skills required “broadly for all workers, consumers and citizens in a digital society” — such as word processing or researching online. Building on that foundation, Intermediate Skills are “effectively job-ready skills needed to perform more complicated work-related functions” such as social media marketing or e-commerce. Advanced or ‘Specialist’ Skills, which “form the basis of specialist occupations and professions,” are necessary to test, analyze, manage, or create digitally based products or services. These advance skills are needed to harness technology to resolve complex problems, guide others such as policymakers, contribute to professional practices, and propose new innovative ideas to advance economic development.
Skills are the supply side of digital labor markets; jobs are the demand side. Digital or ICT work can be conceived in three terms: enhanced, dependent, intensive. Some jobs are enhanced by digital tools, whereas with others — such as Internet freelancing or call centers — technology is fundamental to the work. Digitally intensive work — such as machine learning or app development — requires more specialist and advanced skills.
While data is sparse and likely not as up-to-date as the pace of change, we have learned important baseline details about the digital skills match — or mismatch — in MENA’s digital labor market. There is a shortage of digital human capital in MENA, marked by skills and information gaps. For example, in its 2017Future of Work study, McKinsey found that across the region, only 1.7% of the workforce is ‘digital talent.’ In their last 2017 skills survey of the region, Bayt/YouGov, a leading jobs website in MENA, revealed that IT jobs are among the top open positions, evidence of an acute talent and skills shortage in the region.
The Gulf countries are arguably the most advanced in terms of digital transformation. Yet, GCC countries still have a significant digital skills gap. In a 2020 survey by PwC of CEOs in the Middle East, 70% said the availability of key digital skills is a business threat, and an earlier 2017 study found that only one of the 10 skills most commonly cited by digital professionals in the GCC matches the fastest-growing skills found globally on LinkedIn. Furthermore, none of the top 10 available skills in the GCC is a technical or specific digital skill.
In this blog series, MENA Digital Directions, we will analyze and compare digital skills competence frameworks, discuss how to build digital skills across the educational pipeline, explore the role of the private sector and identify digital opportunities for women, youth and refugees. With a thorough understanding of the digital landscape and the right investments in digital infrastructure and skills, countries can ensure that more young people like Abdullah have a chance for a brighter, more connected future.
