A South African innovator’s journey to create affordable prosthetic legs for amputees

In South Africa, an estimated 300,000 individuals live with amputations, often battling economic hardships while facing the daunting reality of inaccessible prosthetic legs. For many in lower-income households, the possibility of affording quality prosthetics is slim, with costs often surpassing R100,000. Adding to this challenge is a public health system characterised by overwhelming demand and resource scarcity, resulting in unbearably lengthy waiting lists. In the face of this adversity, one entrepreneur’s vision shines brightly.

Seven years ago, Eastern Cape entrepreneur Zanodumo Godlimpi embarked on a mission to create a change. Recently, his determination and innovative spirit were rewarded, as he was named the 2025 EDHE Studentpreneur of the Year at the seventh annual EDHE Entrepreneurship Intervarsity, securing R120,000 for his groundbreaking work. In addition, he captured R25,000 in the Academic Research Commercialisation category.

Godlimpi's acclaimed pneumatic prosthetic foot represents a remarkable leap in prosthetic technology, using air pressure for enhanced mobility. Unlike traditional devices that often rely on complex and costly electrical components, Godlimpi's innovation, predominantly comprised of locally sourced materials, aims to revolutionise accessibility for low and middle-income amputees.

Upon receiving the prestigious award in Johannesburg, an overwhelmed Godlimpi recalled the moment, saying, “I jumped from my seat and rushed to the stage. That moment captured the overwhelming excitement and disbelief I felt.” This accolade not only validates his unwavering commitment but is also a testament to the importance of innovation in addressing dire social challenges.

The pneumatic prosthetic foot is designed specifically for individuals amputated below the knee. Godlimpi explains, “Although many prosthetic devices exist, they are often complex and unaffordable for the intended users.” His prototype operates on principles of simplicity and functionality, making it easier to repair, maintain, and afford.

His journey began during his time studying medicine at Walter Sisulu University, where he witnessed patients struggling with conventional prosthetics. Many were unable to walk normally or navigate uneven terrain effectively. Inspired to improve their plight, Godlimpi used his book allowance to acquire necessary materials for his first prototype.

With promising results, his efforts led to a grant of R485,000 from the Technology and Innovation Agency, propelling his prototype towards practical application. He has since secured patents in South Africa, China, and Europe, marking important milestones in his entrepreneurial journey.

The prize money from the EDHE will be dedicated towards acquiring a 3D printer and facilitating essential travel for further testing phases of his prosthetic foot. “I am currently preparing for the next phase of testing with an increased participant base,” he noted, recognising the importance of validating his innovations thoroughly.

In five years, Godlimpi envisions a company centred on designing and manufacturing diverse prosthetic solutions, accommodating users of varying financial capabilities. He plans to segment his product line from basic models to premium variants featuring AI integration for customised gait assistance.

Godlimpi shares his belief in the value of entrepreneurship competitions, which enable budding innovators to showcase their concepts while gaining vital insights, funding, and mentorship. “These opportunities not only help validate ideas but also build confidence and foster collaborations that can accelerate impactful change,” he stated.

Despite dedicating himself to his project, Godlimpi finds time to unwind, through activities such as gym workouts, watching soccer as a devoted Kaizer Chiefs fan, and practicing carpentry — an art he indulges in during holidays to nurture his creativity.

Grateful for the support he has received throughout this journey, he acknowledges the role of collaboration and community in his success: “My work reflects the unwavering encouragement from the WSU Office of Technology Transfer and our extensive network, making it possible for us to impact lives meaningfully.”
