Revolutionary Prosthetic Ankle

Summary: Prosthetic devices have improved over time due to changes in design and technology. Today, prosthetics play an important role in allowing amputees to have an active lifestyle. However, these devices are still imperfect and do not mimic various aspects of the human body. Current prosthetics are extremely expensive, weigh between 1.5 and 2 pounds, and frequently break or tear. There is room for improvement in the development of prosthetic devices. Researchers at Purdue University have developed a new prosthetic ankle that allows for a wider and more natural range of movement. Made out of aluminum, the prosthetic is composed of a toe joint, a pre-existing incline, and an ankle joint. This device allows for toe flexibility and natural lift, enabling more natural walking, running, and jumping for users. This prosthetic is lightweight, is estimated to last for five years, and costs a fraction of the price compared to existing prosthetics.

Technology Benefits: Wider range of movement Improved natural movement for user Lightweight Durable Low cost

Technology Application: Prosthetics for foot amputees including adolescents, the average person, and athletes
