Are passive prosthesis made of nanotubes?

Passive prostheses are typically not made of nanotubes; they are more commonly constructed from materials like plastics, metals, and composites that provide adequate strength and flexibility. However, researchers are exploring the use of carbon nanotubes in prosthetics to enhance properties such as strength, weight reduction, and flexibility. While nanotube-based materials are still largely in the experimental stage, they hold potential for future advancements in prosthetic technology.
