Onion cells used to create artificial muscles

By adding a bit of gold, artificial muscles can be made from these things (Photo: Shutterstock)

Artificial muscles could one day revolutionize fields such as robotics, prosthetics and nanotechnology. So far, we've seen examples made from materials like electroactive elastomers, crumpled graphene, and vanadium dioxide. The problem is, most artificial muscles can only expand in one direction, or contract in the other. Now, however, scientists from National Taiwan University have gotten around that limitation using gold-plated onion cells.
