Title: Hydraulics? Pneumatics? Screw actuators? Nah, just get knitting!

Need a bit more muscle? Maybe one day you can just slip on a nice, slinky jumper (and a battery pack) and get power lifting.

A cellulose yarn with a special coating, when knitted or woven, may one day form "muscles" for the disabled, and probably other uses.

Neat. And cellulose would be a cheap material.

I remember playing with "memory wire" when I was a kid. Bend it out of shape, apply heat or electricity, and it resumes it's original shape.

Used to have a pair of memory metal spectacles, you could scrunch them up, sit on them, nothing would damage the frame - except a hot air gun would  turn them into a pretzel (I was told).

Fascinating stuff, they made a glass house ventilator with a memmet sensor/actuator and I saw a prototype pump system that used the sun's heat and the cooler water to motivate it. Sterling engine worked better though.

I would have been interested in seeing the stuff in action, but the video only included still images of it.  >:(

Yes, shame that, perhaps its present perfomance is less than impressive? 1 mm per kilovolt!?
