When a body part is damaged it can be possible to repair or replace it. Inventive humans have been crafting artificial body parts since at least the days of Ancient Egypt! For most of our history the design and materials used to make body parts stayed much the same. Since the 20th century, however, engineers have greatly increased the variety and effectiveness of artificial body parts, using new materials and smarter design.
The Artificial Body Zone includes an engineer using 3D printing to make new metal ‘bones’, an engineer who makes robot hands for humans and one who tries to grow new tissues that could be used to cure people with serious illnesses. There’s also an engineer who makes metal surfaces more slippery, another who builds new medical devices for the NHS and one trying to make a robot boy learn how to sit.
