BBC reports that researchers at the University of Texas at Dallas have developed artificial muscles with the strength of a hundred men.
The most powerful type, “shorted fuel cell muscles” convert chemical energy into heat, causing a special shape-memory metal alloy to contract.
Turning down the heat allows the muscle to relax.
Lab tests showed that these devices had a lifting strength more than 100 times that of normal skeletal muscle.
It should be noted that Dallas is north of Austin and the bionic man was Steve Austin. Just keep that in mind. Link.
