Nigerian Female Engineer Invents Smart Bra To Detect Breast Cancer

Nigerian robotics and embedded systems engineer, Kemisola Bolarinwa, has invented a smart bra capable of diagnosing early-stage breast cancer before symptoms develop.

Bolarinwa made the invention known to the world in February 2022, by designing the prototype of the smart bra, which was spurred by the death of her loved one in 2017.

She said before the death of her aunt, she rarely paid any attention to breast cancer because it was just something she heard on the TV or radio.

Bolarinwa, the founder and chief executive officer of Nextwear Technologies, the first wearable technology startup in Nigeria, said she was moved to invent the smart bra, after frequent visits to the hospital where her aunt was before she died.

She said seeing other women battling breast cancer was painful, and her efforts to intensify research into the invention were increased.

Her invention was recognised by BBC Africa, adding that she spent a year and a half of intense research, before the smart bra came up in 2019.

How the smart bra works
To detect lumps in the breast, the smart bra repurposes ultrasound technology into a small form factor, with the initiative to shrink down an ultrasound machine to a portable size where it becomes wearable.

According to Bolarinwa, this was possible with nanotechnology — a branch of science, technology, and engineering that deals with the manufacturing of tech in small sizes.

For more context, the smart bra uses an ultrasound system called the Doppler that bounces high-frequency sound waves off the body to detect blood clots, heart defects, and blocked arteries. This works differently from ultrasound machines that use sound waves to generate images of the scanned area.

More work on the smart bra
After years of research and developing a prototype, she revealed there are still a lot of work to be achieved on the smart bra before it can be commercialised.

Bolarinwa said the smart bra still needs further development and extensive clinical trials and gave a time frame between the end of 2022 and the beginning of 2023 for mass production.

Aside from being an inventor, Bolarinwa is also a strong advocate for getting more women interested in STEM (science, technology, engineering, and mathematics), something she was passionate about growing up.

Bolarinwa called for more work on research for inventions to be effective in solving the problems they are designed for while lamenting there are not adequate research organisations to help.

She said, “In four months, a fintech platform will be built and be ready for the market. This is one of the reasons why few people play in the hardware or deep tech side of technology in Africa. There aren’t enough research institutes.”

Who she is

Bolarinwa holds a Bachelor of Engineering in Electrical, Electronics, and Communications Engineering from the University of Ado-Ekiti (now Ekiti State University).

She has more than 10 years of experience exceptional tech skills and strong problem-solving skills, and is passionate about solving complex problems and staying up-to-date with the latest technologies.

Bolarinwa is an inventor, innovator, entrepreneur, and president of the Women In ICT Foundation, a nonprofit organization that focuses on providing technology education, leadership, and businesses for women and young girls to resolve problems of the under-representation of women in leadership, policy-making, and math-intensive fields of science and technology.

Nigeria is endowed with exceptional and skilled inventors such as the 70-year-old man who developed more than inventions, but the challenge they are faced with is the lack of support from the government and other recognised agencies or entrepreneurs to sponsor their research and inventions.

Africa Coups: 10 In Five Years

Editor

A military coup attempt in Benin Sunday adds to a list of such incidents on the turbulent African continent.
A group of soldiers announced that they had ousted President Patrice Talon, although his entourage said he was safe and the army was regaining control.

Here is a recap of the 10 successful coups in Africa in the last five years:

Mali

Malian President Ibrahim Boubacar Keita is overthrown by five army colonels in August 2020.

In May 2021, the Malian military takes over from the civilian leaders of an interim government.
Colonel Assimi Goita, who led both coups, is sworn in as transitional president.

After promising to hold elections in February 2024, the military puts them off indefinitely, pointing to the jihadist violence plaguing the country.

In July 2025, Goita approves a law granting himself a five-year presidential mandate, renewable without election.
In September jihadists launch a fuel blockade, weakening the ruling junta.

Guinea

On September 5, 2021, mutinous troops led by lieutenant-colonel Mamady Doumbouya take over in Guinea, arresting President Alpha Conde.

Doumbouya in early November 2025 submits his candidacy ahead of December 28 elections that are meant to restore constitutional order.

Sudan

After weeks of tension between the military and civilian leaders who had shared power since the ousting of dictator Omar al-Bashir, the armed forces led by army chief Abdel Fattah al-Burhan stage a new coup on October 25, 2021.

Since April 2023 war has raged between the regular armed forces led by Burhan and the paramilitary Rapid Support Forces, led by his former deputy Mohammed Hamdan Daglo.

The conflict has so far killed tens of thousands of people and created one of the world’s worst humanitarian crises.

Burkina Faso

Burkina Faso underwent two military coups in 2022.

In January that year mutinous soldiers led by Lieutenant-Colonel Paul-Henri Sandaogo Damiba arrest President Roch Marc Christian Kabore.

Then in September army officers announce they have dismissed Damiba. Captain Ibrahim Traore becomes transitional president, but elections he promised do not materialise. In May 2024 the junta authorises him to stay for another five years in a country wracked by Islamist violence.

Niger

On July 26, 2023, members of the presidential guard overthrow Niger’s President Mohamed Bazoum, elected in 2021. General Abdourahamane Tiani, head of the presidential guard, takes over.

In March 2025, the junta extends by at least five years its transitional leadership of the country which is plagued by jihadist violence.

Gabon

In Gabon, ruled for 55 years by the Bongo family, army officers on August 30, 2023 overthrow President Ali Bongo Ondimba, less than an hour after he is declared winner of an election the opposition says was fraudulent.
General Brice Oligui Nguema is named transitional president.

In April 2025 he is elected president with 94.85 percent of the vote. He is sworn in on the basis of a new constitution approved by referendum during the transition.

Madagascar

In October 2025, the military ousts Madagascar’s president Andry Rajoelina and takes power following weeks of “Gen Z” anti-government protests.

Army colonel Michael Randrianirina is sworn in as Madagascar’s new president, promising elections within 18 to 24 months.

Guinea-Bissau

In November 2025, military officers in Guinea-Bissau declare they have “total control” of the coup-prone west African country, closing its borders and suspending its electoral process three days after general elections.

The military says a command “composed of all branches of the armed forces” is taking over the leadership of the country “until further notice”.

Benin Republic Presidency Breaks Silence On ‘Military Takeover’

Benin Republic military
Military personnel in Benin on Sunday said they had ousted President Patrice Talon, but the Presidency said he was safe and the army was regaining control.

Talon, 67, a former businessman known as the “cotton king of Cotonou,” is due to hand over power in April next year after 10 years in office marked by strong economic growth and rising jihadist violence.

West Africa has seen several coups in recent years, including in Niger, Burkina Faso, Mali, Guinea, and most recently Guinea-Bissau.

Early on Sunday, soldiers calling themselves the “Military Committee for Refoundation” (CMR) said on state television that they had met and decided that “Mr Patrice Talon is removed from office as president of the republic.”

The signal was cut later in the morning.

Shortly after the announcement, a source close to Talon told AFP the president was safe.

“This is a small group of people who only control the television. The regular army is regaining control. The city (Cotonou) and the country are completely secure,” they said.

“It’s just a matter of time before everything returns to normal. The clean-up is progressing well.”

A military source confirmed the situation was “under control” and said the coup plotters had not taken Talon’s residence or the presidential offices.

The French Embassy reported on X that “gunfire was reported at Camp Guezo” near the president’s official residence in the economic capital and urged French citizens to remain indoors.

Benin has a history of coups and attempted coups.

Talon, who came to power in 2016, is due to end his second term in 2026, the constitutional maximum.

The main opposition party has been excluded from the race to succeed him, leaving the ruling party to compete against a so-called “moderate” opposition.

Talon has been praised for driving economic development but is often accused of authoritarianism.

A group of soldiers appeared on Benin’s state television on Sunday to announce the dissolution of the government in what is being described as an apparent coup, marking yet another power seizure in West Africa.

Identifying themselves as the Military Committee for Refoundation, the soldiers declared the removal of the president and all state institutions.

President Patrice Talon, who has been in office since 2016, was scheduled to leave office next April after the presidential election. His party’s preferred candidate, former Finance Minister Romuald Wadagni, had been widely viewed as the frontrunner. Opposition candidate Renaud Agbodjo was disqualified by the electoral commission on the grounds that he did not have “sufficient sponsors.”

The takeover comes a month after Benin’s legislature extended the presidential term from five to seven years while retaining the two-term limit.
