Cure BionicsCure Bionics, a startup company based in Tunisia, is finalizing its design for a prosthetic hand using 3D-printed components. Priced at $2,000, the model will cost significantly less than the bionic limbs typically imported from Europe. Cure Bionics could transform the lives of many Tunisians in need of prosthetic limbs to improve their quality of life.

Disabilities in Tunisia

Although not much data is available for limb differences in Africa, the 2002-2004 World Health Survey declared that 16.3 of Tunisia’s population possessed some sort of disability.

Although the country has passed groundbreaking legislation prohibiting discrimination against people with disabilities, prejudice still hinders Tunisians with disabilities from fully participating in social settings. Moreover, people with disabilities often find voting difficult due to a lack of appropriate accommodations and many struggle to find good employment. Past research indicated that nearly 60% of Tunisians with disabilities did not earn any individual income, and the 40% who did work, earned 40% less than people without disabilities.

Social, political and economic exclusion means, broadly speaking, that Tunisians with disabilities are more acutely impacted by multidimensional poverty than Tunisians without disabilities. In turn, this has led to disparities in education, health and employment. The social exclusion of people with disabilities has a considerable cost in terms of quality of life with a life expectancy reduction of approximately 18 years.

Cure Bionics

Cure Bionics hopes to improve the lives of disabled people in Tunisia by making high-tech bionic limbs more accessible and affordable for the people who need them.

When the company’s founder, Mohamed Dhaouafi, was studying engineering at university, he began to research prosthetics after learning that one of his peers had a relative who was born without upper limbs and could not afford prosthetics. Dhaouafi quickly discovered that this is not uncommon: Of the approximately 30 million people in developing countries who have amputated limbs, only 1.5 million can obtain prosthetics.

After graduating from university, Dhaouafi continued to work on the prosthetic device he had begun designing in school. Today, Cure Bionics’ 3D-printed bionic hands have rotating wrists, a mechanical thumb and fingers that bend at the joints in response to the electronic impulses. The bionic hand can be adjusted to accommodate a child’s physical growth. It can also be solar-powered for use in regions without a reliable electricity supply. Since young people with limb differences require multiple prostheses as they age, Cure Bionics’ cost-effective approach could help to ensure that more children benefit from prosthetic limbs earlier in life.

Moreover, Dhaouafi hopes to offer a virtual-reality headset for physical therapy sessions. Geared especially toward children, the headset will allow recipients of bionic limbs to become familiar with their prosthetics and to practice moving and flexing their fingers in the fun and exciting context of a video game.

Looking to the Future

While Cure Bionics continues to finalize and test its bionic hand before making it available for purchase in Tunisia, Dhaouafi has already set himself another goal. He wants to offer high-tech, low-cost prosthetic limbs to people with limb differences throughout Africa, the Middle East and beyond.

Selected by the Obama Foundation Leaders: Africa program in 2019, Dhaouafi is helping to increase access to bionic prosthetics for people who could not otherwise have afforded the expense. In this way, he is also helping Tunisians with limb disabilities to overcome the formidable challenges of exclusion and escape multidimensional poverty,  improving their quality of life overall.

Nanotechnology is Alleviating PovertyIn its most basic sense, the concepts behind nanotechnology were formulated by acclaimed physicist Richard Feynman in 1959. Over the past four decades, nanotechnology has made significant advancements and research is expanding as costs are falling. Because of these innovations, nanotechnology is alleviating poverty worldwide.

Using Nanosensors for Water Management in Agriculture

Whether mechanical or chemical, nanosensors use tools to detect minor changes in chemical composition and relay information to change the dynamics of whatever they are monitoring. Nanosensors use artificial intelligence and computing to make adjustments as soon as any predicaments arise. Because of their sensitivity and small scale, nanosensors can detect problems well before other outdated instruments.

In a study for sustainable agriculture, the Organisation for Economic Co-operation and Development (OECD) asserts nanotechnology is alleviating poverty issues such as food insecurity. The OECD study concluded that nanosensors effectively detect changes in moisture across fields of crops. They then automatically adjust the disbursement of water and eliminate water waste while preventing crop losses. Farm machines outfitted with nanosensors detect moisture levels in different crops and suggest better-suited areas for specific crops allowing farmers to change planting patterns or change water allocations to other land plots.

Nanofiltration Membranes Provide Clean Drinking Water

Access to clean water is a crisis that many developing countries face. Usually, the first issue dealt with when fighting poverty is economic development so regulations are not often in place to protect against pollution. In some countries, scarcity of clean groundwater becomes problematic too. However, nanotechnology is alleviating poverty in these areas by providing clean drinking water.

Ghana was the center of a study on the effectiveness of nanofiltration membranes conducted by the International Water Association (IWA) and members of the Indian Institute of Science. The IWA chose to test Ghana’s groundwater due to the high level of pollutants present. During the study, it tested the levels of contaminants, bacteria and natural materials that render water non-potable before and after utilizing nanofiltration membranes.

The results of the IWA study were impressive. Not only did the study determine that nanofiltration reduces pollutants to potable levels, but executed efficiently enough, rural areas could produce enough water for more than 100 households. Ultimately, the conclusion was that nanofiltration was a low-cost solution for drinking water access and production in impoverished rural regions worldwide.

Nanotechnology to Fight Infectious Disease

Most original concepts of nanotechnology’s usefulness focused on medical care. The World Health Organization (WHO) has long been fond of utilizing nanotechnology in health care and fighting infectious diseases. The WHO now recognizes that nanotechnology is alleviating poverty in developing nations through scientific medical breakthroughs.

The first need for nanotechnology to address in developing countries is the diagnosis of disease. Nanobiotechnology allows for an inexpensive option to find multiple dangerous microbes using a single test. These technologies have improved over time and are being used in developing nations to detect most viral and bacterial infections, including tuberculosis.

The COVID-19 vaccine development shows the importance of nanotechnology in the prevention of disease too. The Pfizer and Moderna vaccines use a nanocarrier system designed to activate the immune system to fight COVID-19 by assisting antibody production. The distribution of the vaccine to developing nations is now underway.

The Future of Nanotechnology for Poverty Reduction

Nanotechnology is alleviating poverty in developing nations, and with continued scientific inquiry and advancements in nanotechnology, new applications for poverty reduction will improve. Nanotechnology’s cost-effectiveness and versatility make it one of the most viable technologies to assist in the struggle against poverty.
