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 by the user's muscle signals or through a computer interface, providing a more intuitive experience. The development of bionic limbs has been greatly influenced by fields such as robotics and biomedical engineering. Innovations in materials and sensors have led to lighter, more durable designs that enhance mobility and comfort. As technology continues to advance, bionic limbs are becoming increasingly sophisticated and accessible for those in need.
