Prosthetic devices are artificial tools designed to replace missing body parts, helping individuals regain functionality and improve their quality of life. Common examples include prosthetic limbs like arms and legs, which allow users to perform daily activities such as walking, running, or grasping objects. These devices are tailored to fit each person's unique needs and can be made from various materials, including plastic, metal, and carbon fiber. Advancements in technology have led to the development of more sophisticated prosthetics, such as bionic limbs that can be controlled by the user's thoughts. These innovative devices often incorporate sensors and motors, providing a more natural movement and enhancing the user's ability to interact with their environment.
