The exhibition also has a large selection of real-world prosthetic devices which are "becoming quite extraordinary".

"We have the capacity now for the signal to go through the processing devices within the prosthesis and into the brain so it can twitch the nerves," Connell said. "Basically, the muscle in the nerves under the skin can take stimulus from the end of the prosthetic limb then drive it back again. So this is able to act like a knee. I believe there is a pilot who is flying again with one of these after losing his leg."

Examples of biohybridization include the Boston Digital Arm and growing skin so it fits to metal. There is an example of artificial, but biological, skin grown for a skin graft and bionic implants which are planted into muscle and used to stimulate the muscles to keep them alive and working.

"The brain gauge can be put into the brain and signals can be used from the brain directly to make things happen in the world so the idea is just by thinking, or learning to think, we can drive things," Connell said.

"I'm very interested in human-computer interaction. At one end of the spectrum we actually build artificial humans like C3-PO who can talk to us and the other end is where we connect our wires to the computer's wire and they disappear to us."
