How to Build a Bionic Man
Rex the bionic man shows how close technology is to catching up with – and exceeding – the abilities of the human body
He cuts a dashing figure, this gentleman: nearly seven feet tall, and possessed of a pair of striking brown eyes. With a fondness for Ralph Lauren, middle-class rap and sharing a drink with friends, Rex is, in many ways, an unexceptional chap.
Except that he is, in fact, a real-world bionic man. Housed within a frame of state-of-the-art prosthetic limbs is a functional heart-lung system, complete with artificial blood pumping through a network of pulsating modified-polymer arteries. He has a bionic spleen to clean the blood, and an artificial pancreas to keep his blood sugar on the level. Behind the deep brown irises are a pair of retinal implants, giving him a vista of the crowds of curious humans who meet his gaze.
He even has a degree of artificial intelligence: talk to him, and he’ll listen (through his cochlear implants), before using a speech generator to respond. Although, like us, he sometimes stumbles over his words, memorably describing his idol Eminem as a “well-known crapper”, before quickly correcting himself.
