In the city of Yaoundé, Cameroon, a young man named Arthur Zang grew up with a dream bigger than the challenges around him. Born on November 26, 1987, in the small town of Mbankomo, Zang witnessed firsthand the struggles of a nation where access to healthcare was a luxury many couldn’t afford. With only a handful of cardiologists serving millions, rural communities were left vulnerable, especially to heart disease—an emerging health crisis in Cameroon. Today, at 37, Zang is celebrated as the mastermind behind the CardioPad, a groundbreaking medical tablet that’s bringing cardiac care to the farthest corners of the continent.
Zang’s journey into innovation began with a simple observation during a college internship at a local hospital in Yaoundé. While studying computer science at the University of Yaoundé—where he earned a bachelor’s degree in 2004 and later a master’s in software engineering from the National Advanced School of Engineering in 2010—he worked under the guidance of cardiologist Samuel Kingue. There, he saw the stark reality: Cameroon had just 30 cardiologists for a population of over 20 million. Patients in remote areas faced impossible odds, often traveling hundreds of miles for a diagnosis they might not survive to receive.
It was a personal loss that cemented his resolve. While developing his invention, Zang’s uncle died of a stroke—a tragedy that hit close to home. “That gave me extra motivation to see the project through,” Zang later shared. What started as a spark of curiosity became a mission to bridge the healthcare gap using technology.
The result of Zang’s determination is the CardioPad, Africa’s first touch-screen medical tablet designed for remote cardiac diagnosis. Picture this: a device roughly the size of an iPad mini, equipped with wireless electrodes that attach to a patient’s chest. It records an electrocardiogram (ECG), capturing the heart’s electrical activity, and transmits the data over mobile networks to a cardiologist anywhere in the world. Within minutes, a diagnosis and treatment plan can be sent back—no travel required.
Zang taught himself electronics online to build the hardware, merging it seamlessly with his software expertise. The initial prototype used four sensors, but with time and funding, he upgraded it to a 12-sensor model for more comprehensive heart analysis. Priced at around $3,200 per unit, the CardioPad is a fraction of the cost of traditional ECG machines, yet it delivers life-saving results to places where such technology was once unimaginable.
Bringing the CardioPad to life wasn’t easy. Funding was a constant hurdle in a country where banks demanded guarantees Zang couldn’t provide. Undeterred, he turned to the internet, posting videos about his project on YouTube and Facebook. His persistence paid off when the Cameroonian government took notice, granting him $20,000 to build his first prototypes. Two units were soon tested in hospitals, proving their worth.
In 2014, Zang’s innovation caught global attention when he won the Rolex Award for Enterprise, providing funds to produce 100 more CardioPads—one for each of Cameroon’s provinces. Later that year, the UK’s Royal Academy of Engineering awarded him the Africa Prize for Engineering Innovation, further validating his impact. With this support, Zang founded Himore Medical Equipments, a company that has since sold nearly 70 CardioPads across Cameroon, India, Nepal, and Gabon.
Zang’s vision doesn’t stop at heart care. In 2020, as the world grappled with COVID-19, he unveiled Oxynnet—a network of connected oxygen production stations to aid patients with respiratory illnesses. This new invention reflects his relentless drive to address Africa’s healthcare challenges with practical, scalable solutions. He’s also hinted at future projects, like affordable ultrasound machines and emergency alert systems for rural patients.
Through the Africa Cardiac Care Program, launched in 2016, Zang ensures low-income patients receive annual cardiac screenings, making healthcare not just accessible but equitable. “Millions can benefit from our work,” he says, his eyes set on expanding across Africa and beyond.
At 37, Arthur Zang is more than an inventor—he’s a symbol of what’s possible when ingenuity meets compassion. His story resonates with young Africans, proving that world-changing ideas can emerge from anywhere, even a small town in Cameroon. Recognized by TIME as one of the “30 People Under 30 Changing the World” in 2013 and Forbes’ “30 Under 30” list, Zang’s accolades are impressive, but his true measure of success lies in the lives he’s touched.
From sketching algorithms on a glass window to leading Himore Medical, Zang has turned hardship into hope. His CardioPad isn’t just a device—it’s a lifeline, pulsing with the promise of a healthier future for millions. As he continues to innovate, one thing is clear: Arthur Zang’s heart beats for progress, and the world is listening.
