Tunisian AI expertise to benefit Africans in need of artificial limbs

  • Dismayed by the lack of affordable prosthetics, Mohamed Dhaouafi created his own range of low-cost artificial hands
  • High cost and limited availability mean just 5 percent of people in the developing world who need prosthetics have artificial limbs 

TUNIS: Mohamed Dhaouafi began researching prosthetics in 2016 as part of a university project. He swiftly realized there was a lack of readily available and affordable prosthetics, with artificial hands costing up to $50,000.

After finishing his studies, Dhaouafi, 28, ran a startup incubator ZETA HUB at a private university to earn an income while continuing his work on prosthetics. He launched CURE Bionics in late 2018, going full time with his Sousse-based startup in 2019.

Having made multiple prototypes to perfect the design of its prosthetics, the five-strong team decided to launch its products commercially in the first half of 2021.

“We want people using our prosthetics to be satisfied and use it in a practical way — we want our patients to be able to rely on our prosthetics and to guarantee they will last,” said Dhaouafi, CURE’s CEO.

“We’re making some final improvements and will then launch a pilot. If that goes well, we’ll quickly launch in Tunisia before expanding abroad. Tunisia is a tough market, so if we succeed here, we can succeed elsewhere.”

In the developing world, only 5 percent of the 40 million people needing prosthetics have artificial limbs due to the high cost and limited availability. Among those who have received them, nearly 70 percent are dissatisfied and 52 percent reject them, a 2019 University of Nebraska study found.

“People generally feel comfortable wearing a prosthetic, but controlling it is very difficult and complicated. Ours are easy to use since they’re very intuitive,” said Dhaouafi.

The lightweight, 3D-printed artificial hands come with different functions depending on the task the patient wants to perform. The brain tells the limbs to move via electric signals transmitted through the nerves, instructing the appropriate muscles to contract or relax.

CURE’s prosthetic hands deploy artificial intelligence (AI) to read these signals via sensors placed on the skin, which means no surgery is necessary to fit them.

“People suffer different traumas in losing their hands. Some were born without hands, so they never experienced what it means to open and close a hand — their muscle signals will be either weak or absent,” said Dhaouafi.

“These differences can be problematic, so the AI algorithm learns and identifies what the muscle signal is about. By using AI, we can reduce the need for doctors and engineers in teaching patients how to use a prosthetic. If they have to intervene with every patient, we cannot scale the product fast. So we made the algorithm smarter.”

CURE’s patients will master the necessary movements through conscious repetition, imprinting them into their subconscious mind so that they can act without thinking — much like how one learns to ride a bike. To help its patients, CURE has developed a virtual reality training program.

“In the virtual environment, they can manipulate the virtual hand like a prosthetic, but in a gamified way to master the exercises while having fun,” Dhaouafi said. “It’s intuitive training. The doctor can provide therapy remotely without the patient having to visit them in person.”

In developing countries, large swathes of the population lack reliable electricity. Consequently, prosthetics users may be unable to recharge the batteries in their artificial limbs, so CURE’s products will come with a solar-powered wireless charger.

“By adding this feature, we can help more people,” said Dhaouafi.

The prosthetic hands come in various predefined sizes, while the socket is fully customizable. They will likely cost between $2,500-3,000, depending on the specific features the patient requests.

Outside Tunisia, CURE will sell its products through third parties that will conduct product measurement, 3D printing, assembly, fitting, and after-sales service.

“That’s the best way for us to scale fast,” Dhaouafi said.

The company is in negotiations with potential partners across Africa, with priority markets including Nigeria, South Africa, Morocco, Egypt, and Angola.

“I visited many of these countries and know people there,” said Dhaouafi, who has participated in non-profit programs in the target markets. “It’s about finding the right partner.”

Helicopter carrying Iran's President Raisi makes rough landing, Iranian media say

  • IRNA said the helicopter in question had been carrying Raisi, Foreign Minister Hossein Amirabdollahian and local officials

DUBAI: A helicopter carrying Iranian President Ebrahim Raisi and his foreign minister made a rough landing on Sunday as it was crossing a mountainous area in heavy fog on the way back from a visit to Azerbaijan, Iranian news agencies said.
The bad weather was complicating rescue efforts, the state news agency IRNA reported. The semi-official Fars news agency urged Iranians to pray for Raisi and state TV carried prayers for his safety.
IRNA said the helicopter in question had been carrying Raisi, Foreign Minister Hossein Amirabdollahian and local officials.
Interior Minister Ahmed Vahidi told state TV only that one of the helicopters in a group of three had come down hard, and that authorities were awaiting further details.
Raisi, 63, was elected president at the second attempt in 2021, and since taking office has ordered a tightening of morality laws, overseen a bloody crackdown on anti-government protests and pushed hard in nuclear talks with world powers.
In Iran’s dual political system, split between the clerical establishment and the government, it is the supreme leader rather than the president who has the final say on all major policies.
But many see Raisi as a strong contender to succeed his mentor, Supreme Leader Ayatollah Ali Khamenei, who has strongly endorsed Raisi's main policies.

Israel war cabinet minister says to quit unless Gaza plan approved

  • Israeli PM Benjamin Netanyahu dismisses comments as "washed-up words"
  • Broad splits emerge in Israeli war cabinet as Hamas regroups in northern Gaza

JERUSALEM: Israeli war cabinet minister Benny Gantz said Saturday he would resign from the body unless Prime Minister Benjamin Netanyahu approved a post-war plan for the Gaza Strip.

“The war cabinet must formulate and approve by June 8 an action plan that will lead to the realization of six strategic goals of national importance.. (or) we will be forced to resign from the government,” Gantz said, referring to his party, in a televised address directed at Netanyahu.

Gantz said the six goals included toppling Hamas, ensuring Israeli security control over the Palestinian territory and returning Israeli hostages.

“Along with maintaining Israeli security control, establish an American, European, Arab and Palestinian administration that will manage civilian affairs in the Gaza Strip and lay the foundation for a future alternative that is not Hamas or (Mahmud) Abbas,” he said, referring to the president of the Palestinian Authority.

He also urged the normalization of ties with Saudi Arabia “as part of an overall move that will create an alliance with the free world and the Arab world against Iran and its affiliates.”

Netanyahu responded to Gantz’s threat on Saturday by slamming the minister’s demands as “washed-up words whose meaning is clear: the end of the war and a defeat for Israel, the abandoning of most of the hostages, leaving Hamas intact and the establishment of a Palestinian state.”

The Israeli army has been battling Hamas militants across the Gaza Strip for more than seven months.

But broad splits have emerged in the Israeli war cabinet in recent days after Hamas fighters regrouped in northern Gaza, an area where Israel previously said the group had been neutralized.

Netanyahu came under personal attack from Defense Minister Yoav Gallant on Wednesday for failing to rule out an Israeli government in Gaza after the war.

The Gaza war broke out after Hamas’s attack on October 7 on southern Israel which resulted in the deaths of more than 1,170 people, mostly civilians, according to an AFP tally of Israeli official figures.

The militants also seized about 250 hostages, 124 of whom Israel estimates remain in Gaza, including 37 the military says are dead.

Israel’s military retaliation against Hamas has killed at least 35,386 people, mostly civilians, according to the Hamas-run Gaza’s health ministry, and an Israeli siege has brought dire food shortages and the threat of famine.


US, Iranian officials met in Oman after Israel escalation

US, Iranian officials met in Oman after Israel escalation

  • Washington called on Tehran to rein in proxy forces
  • Officials sat in separate rooms with Omani intermediaries passing messages

LONDON: US and Iranian officials held talks in Oman last week aimed at reducing regional tensions, the New York Times reported.

Through intermediaries from Oman, Washington’s top Middle East official Brett McGurk and the deputy special envoy for Iran, Abram Paley, spoke with Iranian counterparts.

It was the first contact between the two countries in the wake of Iran’s retaliatory missile and drone attack on Israel in April.

The US officials, who communicated with their Iranian counterparts in a separate room — with Omani officials passing on messages — requested that Tehran rein in its proxy forces across the region.

The US has had no diplomatic contact with Iran since 1979, and communicates with the country using intermediaries and back channels.

Since the outbreak of the Gaza war last October, Iran-backed militias — including Hezbollah in Lebanon, the Houthis in Yemen, and armed groups in Syria and Iraq — have ramped up attacks on Israeli and American targets.

But US officials have determined that neither Hezbollah nor Iran want an escalation and wider war.

After Israel struck Iran’s consulate in Damascus at the beginning of April, Tehran retaliated with hundreds of ballistic missiles and drones.

The attack — which was intercepted by air defense systems from Israel, the US and the UK, among others — was the first ever direct Iranian strike on Israel, which has for years targeted Iranian assets in Syria, whose government is a close ally of Tehran.

National Security Adviser Jake Sullivan said in a news conference this week that the “Iranian threat” to Israel and US interests “is clear.”

He added: “We are working with Israel and other partners to protect against these threats and to prevent escalation into an all-out regional war through a calibrated combination of diplomacy, deterrence, force posture adjustments and use of force when necessary to protect our people and to defend our interests and our allies.”

Death toll from Israeli strike on Nuseirat rises to 31: Gaza officials

  • Rescue workers continuing to search for missing people under the rubble
  • Heavy Israeli bombardments have been reported in the central Nuseirat camp

GAZA STRIP, Palestinian Territories: Gaza’s civil defense agency said Sunday that an Israeli air strike targeting a house at a refugee camp in the center of the Palestinian territory killed at least 31 people, updating an earlier toll.

“The civil defense crew were able to recover 31 martyrs and 20 wounded from a house belonging to the Hassan family, which was targeted by the Israeli occupation forces in the Nuseirat camp,” Gaza civil defense agency spokesman Mahmud Bassal told journalists.

He said rescue workers were continuing to search for missing people under the rubble.

Earlier on Sunday the Al-Aqsa Martyrs Hospital had said it had received the bodies of 20 people killed in the strike which witnesses said occurred around 3:00 am local time.

The Israeli army when contacted by AFP asked for specific coordinates of the strike.

Palestinian official news agency Wafa reported that the wounded included several children.

Fierce battles and heavy Israeli bombardments have been reported in the central Nuseirat camp since the military launched a ground operation on the southern city of Rafah in early May.

Palestinian militants and Israeli troops have also clashed in north Gaza’s Jabalia camp for days now.

Witnesses said several other houses were targeted in air strikes during the night across Gaza, and that strikes and artillery shelling also hit parts of Rafah during the night.

The Israeli military said two more soldiers were killed in Gaza the previous day.

The military said 282 soldiers have been killed so far in the Gaza military campaign since the start of the ground offensive on October 27.


Houthi missile strikes China-bound oil tanker in Red Sea

Houthi missile strikes China-bound oil tanker in Red Sea

  • The vessel and crew are safe and continuing to its next port of call: UKMTO
  • The incident occurred 76 nautical miles (140 kilometers) off Yemen’s Hodeidah

AL-MUKALLA: Yemen’s Houthi militia launched an anti-ship ballistic missile into the Red Sea on Saturday morning, striking an oil tanker traveling from Russia to China, according to US Central Command, the latest in a series of Houthi maritime strikes. 

CENTCOM said that at 1 a.m. on Saturday, a Houthi anti-ship ballistic missile struck a Panamanian-flagged, Greek-owned and operated oil tanker named M/T Wind, which had just visited Russia and was on its way to China, causing “flooding which resulted in the loss of propulsion and steering.”

Slamming the Houthis for attacking ships, the US military said: “The crew of M/T Wind was able to restore propulsion and steering, and no casualties were reported. M/T Wind resumed its course under its power. This continued malign and reckless behavior by the Iranian-backed Houthis threatens regional stability and endangers the lives of mariners across the Red Sea and Gulf of Aden.”

Earlier on Saturday, two UK naval agencies said that a ship sailing in the Red Sea suffered minor damage after being hit by an item thought to be a missile launched by Yemen’s Houthi militia from an area under their control.

The UK Maritime Trade Operations, which monitors ship attacks, said on Saturday morning that it received an alarm from a ship master about an “unknown object” striking the ship’s port quarter, 98 miles south of Hodeidah, inflicting minor damage.

“The vessel and crew are safe and continuing to its next port of call,” UKMTO said in its notice about the incident, encouraging ships in the Red Sea to exercise caution and report any incidents.

Hours earlier, the same UK maritime agency stated that the assault happened 76 nautical miles northwest of Hodeidah.

Ambrey, a UK security firm, also reported receiving information regarding a missile strike on a crude oil tanker traveling under the Panama flag, around 10 nautical miles southwest of Yemen’s government-controlled town of Mokha on the Red Sea, which resulted in a fire on the ship.

The Houthis did not claim responsibility for fresh ship strikes on Saturday, although they generally do so days after the attack.

Since November, the Houthis have seized a commercial ship, sunk another, and claimed to have fired hundreds of ballistic missiles at international commercial and naval ships in the Gulf of Aden, Bab Al-Mandab Strait, and Red Sea in what the Yemeni militia claims is support for the Palestinian people.

The Houthis claim that they solely strike Israel-linked ships and those traveling or transporting products to Israel in order to pressure the latter to cease its war in Gaza.

The US responded to the Houthi attacks by branding them as terrorists, forming a coalition of marine task forces to safeguard ships, and unleashing hundreds of strikes on Houthi sites in Yemen.

Local and international environmentalists have long warned that Houthi attacks on ships carrying fuel or other chemicals might lead to an environmental calamity near Yemen’s coast.

The early warning came in February when the Houthis launched a missile that seriously damaged the MV Rubymar, a Belize-flagged and Lebanese-operated ship carrying 22,000 tonnes of ammonium phosphate-sulfate NPS fertilizer and more than 200 tonnes of fuel while cruising in the Red Sea. 

The Houthis have defied demands for de-escalation in the Red Sea and continue to organize massive rallies in regions under their control to express support for their campaign. On Friday, thousands of Houthi sympathizers took to the streets of Sanaa, Saada, and other cities under their control to show their support for the war on ships.

The Houthis shouted in unison, “We have no red line, and what’s coming is far worse,” as they raised the Palestinian and militia flags in Al-Sabeen Square on Friday, repeating their leader’s promise to intensify assaults on ships.

Meanwhile, a Yemeni government soldier was killed and another was injured on Saturday while fending off a Houthi attack on their position near the border between the provinces of Taiz and Lahj.

According to local media, the Houthis attacked the government’s Nation’s Shield Forces in the contested Hayfan district of Taiz province, attempting to capture control of additional territory.

The Houthis were forced to stop their attack after encountering tough resistance from government troops.

The attack occurred a day after the Nation’s Shield Forces sent dozens of armed vehicles and personnel to the same locations to boost their forces and repel Houthi attacks.
