How do fake limbs work?

Fake limbs, or prosthetics, function by mimicking the appearance and function of natural limbs. They are typically designed using lightweight materials like carbon fiber or plastics and can be customized to fit the user’s body. Advanced prosthetics may incorporate sensors, motors, and Artificial Intelligence to enable movement and provide feedback, allowing users to perform actions like walking or gripping objects. These devices can be controlled through residual muscle signals or other input methods, enhancing mobility and functionality for the wearer.
