presented by Engineer Aya Talib Hassan Prosthetics represent one of the most significant applications of biomedical engineering, as they bridge technology, medicine, and human sciences to The Evolution of Prosthetics Over Time Prosthetic limbs are no longer simple traditional replacements; over the decades, they have evolved into advanced engineering systems powered by artificial intelligence and modern materials. In the past, prosthetics were made of wood or basic metals, whereas today they are manufactured using lightweight materials such as carbon fiber and advanced polymers, offering higher strength, reduced weight, and improved user comfort. Biomedical Engineering and Its Role in Development Biomedical engineering plays a central role in the design of modern prosthetics by integrating sensors and micro-control systems that enable more natural movement. In addition, modern technologies such as 3D printing have contributed to producing customized prosthetic limbs tailored to individual cases, enhancing precision and user adaptability. Types of Prosthetic Limbs Prosthetics vary depending on the level and function of amputation, and the most common types include: Upper limb prosthetics: used to replace hands and arms, often controlled through muscular or neural signals. Lower limb prosthetics: used to replace legs and feet, focusing on balance and natural movement. Smart prosthetics: rely on neural or muscular signals to achieve near-natural motion control. The Human and Social Dimension The role of prosthetics extends beyond technical functionality to a deeply human dimension, as they help reintegrate individuals into society and enable independent daily living. They also contribute to enhancing self-confidence and improving the psychological well-being of users. Future Challenges Despite significant advancements, challenges remain, including high costs, the need to improve sensory feedback, and enhancing the integration between the nervous system and prosthetic devices. However, rapid progress in artificial intelligence and robotics promises a more advanced and realistic future. Conclusion Today, prosthetics represent a sophisticated model of integration between engineering and medical sciences. They are no longer just functional replacements but a means of restoring hope and empowering individuals to regain their abilities and actively participate in society.
