David Moinina Sengeh: The sore problem of prosthetic limbs

Decades ago, a civil war in Sierra Leone left thousands as amputees. Researcher and current Education Minister David Moinina Sengeh set out to help them with a more comfortable socket for prostheses. David Moinina Sengeh is a biomechatronics engineer and the current Minister of Education and Chief Innovation Officer in his home country of Sierra Leone. He pioneered a new system for creating prosthetic sockets, which fit a prosthetic leg onto a patient's residual limb. Using multiple technologies, Sengeh created sockets that are far more comfortable than traditional ones, and can be produced cheaply and quickly.
