Subject: Real Techno-Trousers
Techno-Trousers refers to the delightful Wallace & Gromit animation
"The Wrong Trousers." If you haven't seen it, seek it out.
But in any case, real techno-trousers seem to have arrived, though
nothing is said about the power source. --PJK

'POWER PANTS' PROVIDE SUPERHUMAN STRENGTH
Researchers at Nagasaki University, working in collaboration with
scientists at the University of Electro-Communications in Tokyo and
the University of California, Irvine, have built a pair of "power
pants" that can be strapped on to greatly enhance the wearer's
strength. The pants contain computerized sensors that detect how
the wearer is moving his or her leg and hip muscles -- doing deep
knee bends, for instance -- and tubelike artificial muscles
positioned on either side of the knee expand and contract using
compressed air flow. A human tester was able to do 90 squats in 90
seconds while holding a 16-kilogram barbell on his shoulders
without breaking a sweat. This latest artificial body enhancement is
a big improvement on previous versions, says Ephrahim Garcia, a
mechanical and aerospace engineer at Cornell University: "This is
novel because it's sensing over the entire soft-tissue interface of
the body. You need intense amounts of computation to pull it off."
The robotic pants are being tested at Nagasaki University for use
as a physical therapy tool for bed-ridden patients. Researchers are
also testing a mechanical glove that enables the user to pick up a
cup of coffee just by tensing his or her upper arm muscles. "We're
trying to reduce fatigue and eventually help disabled people," says
UC Irvine civil engineer Maria Feng. Widespread testing of the
devices is expected in the next two years, with commercial rollout
in five to ten years. (Technology Review Feb 2004)
