In this Catalyst, Dr Nikki Stamp meets three remarkable Australians whose lives are about to be transformed forever - a girl about to receive her first artificial hand, a deaf woman having a bionic ear switched on and a Paralympian testing the world?s most high-tech foot system. In Berlin, Nikki meets a man with one of the most advanced prosthetic hands in the world, and in London, a man who is using robotics to walk again. Back in Australia, Nikki meets scientists who make her rethink our bionic future - from 3D printing of biological body parts, to moving a robotic arm with her mind and seeing a lab-grown mini-brain as advanced as that of a 10-week-old foetus. As Nikki meets people whose lives are being transformed by the merging of biology with technology, and scientists working in bio-technology, she uncovers a world on the cusp of a bionic revolution.
