Inventor of the Cardiopad - Mobile Heart Care for Africa
Born 1987
🇨🇲 Cameroon Medicine & HealthcareArthur Zang was born in 1987 in Cameroon, a country in Central Africa where, like much of the continent, access to specialized medical care is severely limited. While growing up, Zang witnessed firsthand the healthcare challenges facing his country: a critical shortage of doctors, almost no specialist physicians outside major cities, inadequate medical equipment, and infrastructure gaps that left millions without access to basic healthcare, let alone specialized cardiac treatment.
In Cameroon, a nation of 25 million people, there were fewer than 30 cardiologists, almost all concentrated in the two largest cities, Yaoundé and Douala. For the millions living in rural areas, seeking cardiac care meant traveling hundreds of kilometers to these urban centers—a journey that was prohibitively expensive, time-consuming, and often impossible for poor, sick, or elderly patients. Many people with treatable heart conditions simply died because they couldn't access a cardiologist.
Zang pursued computer engineering studies at the National Polytechnic Institute in Yaoundé, excelling in his coursework and demonstrating exceptional talent in software and hardware development. But rather than following the typical path of seeking employment abroad or in the private sector, Zang became obsessed with a question: could technology solve Cameroon's healthcare access problem? Could he create something that would bring medical expertise to patients, rather than requiring patients to travel to medical expertise?
In 2009, while still a student, Arthur Zang began developing what would become the Cardiopad—a medical tablet specifically designed for cardiovascular examinations in resource-limited settings. The concept was revolutionary yet practical: create a portable, affordable device that nurses and general practitioners in rural clinics could use to perform electrocardiogram (ECG) tests, then transmit the results wirelessly to cardiologists in urban medical centers for diagnosis and treatment recommendations.
The technical challenges were formidable. Zang had to design custom hardware that could accurately capture cardiac signals, develop software to process and transmit the data securely, ensure the device could function in areas with unreliable electricity and internet connectivity, and make it affordable enough for widespread deployment in low-resource settings. He had no major funding, no corporate backing, and no team of engineers—just his own knowledge, determination, and vision.
Working in makeshift laboratories and often using his own limited funds, Zang spent two years developing the first Cardiopad prototype. In 2011, at just 24 years old, he successfully completed the device. The Cardiopad featured:
When Zang first presented his invention, he faced considerable skepticism. Many doubted that a young Cameroonian engineer with no medical background could create a viable medical device. Some questioned whether African-developed technology could meet international medical standards. Others doubted there was a market for such a device. The medical establishment, regulatory bodies, and potential investors were all initially reluctant to embrace his innovation.
But Zang persisted. He conducted rigorous testing, collaborated with cardiologists to validate the device's accuracy, and demonstrated the Cardiopad's effectiveness in real-world clinical settings. The results were undeniable: the Cardiopad provided accurate cardiac readings that cardiologists could use to diagnose conditions and recommend treatments, and it did so at a fraction of the cost of traditional equipment while being portable enough to use anywhere.
In 2012, Arthur Zang became the first Cameroonian to receive the country's Presidential Award of Excellence for Innovation, presented by President Paul Biya. This recognition brought national attention to his invention and validated his approach. International recognition followed: the African Innovation Prize, the Rolex Award for Enterprise, and acknowledgment from the World Health Organization as an example of innovative solutions to Africa's healthcare challenges.
By 2014, Zang had founded Himore Medical, a company dedicated to manufacturing and distributing the Cardiopad and other medical technologies across Africa. The Cameroonian government ordered devices for deployment in rural health centers, and other African countries began expressing interest. The Cardiopad started appearing in clinics across Cameroon, enabling nurses and general practitioners to perform cardiac examinations and receive expert diagnoses within hours rather than requiring patients to travel for days.
The impact was profound and immediate. Patients in remote villages who would never have seen a cardiologist could now receive cardiac care. Early detection of heart conditions became possible in areas where previously, people simply died from undiagnosed and untreated cardiac problems. The Cardiopad exemplified the potential of appropriate technology—not necessarily the most advanced technology available globally, but technology specifically designed for the needs, resources, and conditions of the communities it served.
Zang didn't stop with the Cardiopad. His company continued developing medical technologies addressing Africa's specific healthcare needs, including devices for monitoring other vital signs and conditions. He became a prominent advocate for African innovation, arguing that Africans must develop technological solutions to African problems rather than simply importing expensive foreign technology designed for different contexts.
The Cardiopad brings life-saving cardiac care to millions in rural Africa who would otherwise have no access to cardiologists, demonstrating how locally-developed technology can solve local challenges.
Arthur Zang's story represents a powerful counter-narrative to common assumptions about technology, innovation, and Africa. For too long, the dominant story has been one of Africa as a recipient of technology developed elsewhere, a continent of consumers rather than creators, problems rather than solutions. Zang's invention of the Cardiopad challenges this narrative fundamentally.
The Cardiopad is significant not just as a medical device, but as proof of concept: Africans can develop cutting-edge technology that addresses African needs better than imported solutions. The device works in contexts where expensive Western medical equipment often fails—areas with unreliable electricity, limited internet connectivity, few trained specialists, and severe resource constraints. It succeeds because it was designed specifically for these conditions by someone who understands them intimately.
Zang's work has inspired a generation of young African innovators who see that they don't need to leave the continent or work for foreign companies to make meaningful technological contributions. His success demonstrates that African engineers, working in African institutions, using African resources, can create world-class innovations that save lives and transform communities.
The broader impact of the Cardiopad extends beyond cardiac care. It has opened discussions about telemedicine's potential across Africa, where the ratio of doctors to patients is among the lowest in the world. If cardiac examinations can be conducted remotely with specialist consultation via wireless networks, the same model could work for other medical conditions. The Cardiopad has become a template for how mobile technology can bridge healthcare access gaps.
Zang has also become an advocate for supportive innovation ecosystems in Africa. He speaks publicly about the challenges he faced—lack of funding, skepticism from established institutions, regulatory hurdles, and difficulties accessing components and manufacturing capabilities. His advocacy has helped spark conversations about how African governments and institutions can better support local innovators and entrepreneurs.
Today, Arthur Zang continues his work through Himore Medical, developing additional medical technologies and expanding the Cardiopad's reach. His vision is clear: Africa should not merely consume technology developed elsewhere but should become a center of innovation creating solutions that work for African contexts and can potentially benefit the world. The Cardiopad is just the beginning of what he believes African innovation can achieve.
