Prosthetic devices are artificial limbs or body parts designed to replace missing or damaged ones. They help individuals regain mobility and perform daily activities. Common types include prosthetic arms, prosthetic legs, and prosthetic hands, each tailored to meet the specific needs of the user. These devices can be made from various materials, such as plastic, metal, and carbon fiber, ensuring durability and comfort. Advances in technology have led to the development of bionic prosthetics, which can mimic natural movement and even respond to the user's thoughts, enhancing the overall quality of life for those with limb loss.
