Just as controlled-release medications slowly dole out their cargo after they experience a pH change in the body, implanted “artificial muscles” could someday flex and relax in response to a light illuminating the skin. In pilot studies, scientists have developed a new material that expands and contracts, lifting a weight merely by shining a light […]
