Bionic limbs are advanced prosthetic devices designed to replace missing or damaged arms and legs. They use technology to mimic the natural movement of human limbs, allowing users to perform everyday tasks more easily. These devices can be controlled through muscle signals or even brain activity, providing a more intuitive experience for the user. The development of bionic limbs has been greatly influenced by advancements in robotics and materials science. Many bionic limbs are equipped with sensors that help them respond to the environment, improving functionality. Researchers continue to explore ways to enhance these devices, making them more accessible and effective for individuals with limb loss.
