Phys.org reports on a new synthetic gel able to produce movement using its own internal chemical reactions.
For decades, robots have advanced the efficiency of human activity. Typically, however, robots are formed from bulky, stiff materials and require connections to external power sources; these features limit their dexterity and mobility. But what if a new material would allow for development of a "soft robot" that could reconfigure its own shape and move using its own internally generated power?
By developing a new computational model, researchers at the University of Pittsburgh's Swanson School of Engineering have designed a synthetic polymer gel that can utilize internally generated chemical energy to undergo shape-shifting and self-sustained propulsion.
With other recent gel developments that Phys.org has reported, along with the advancement of AI, one must wonder if we are approaching sci-fi tech similar to the T-1000 from the Terminator series.

Lord Corporation (or someone else?) figured out the magnetic fluid thing and it's been used in dampers (shock absorbers) in a number of high end cars, Corvette, Cadillac/Buick and I think licensed to Ferrari in one case. Marketed by Delphi (former Delco) as "MagneRide" http://en.wikipedia.org/wiki/MagneRide [wikipedia.org]
This article talks a bit about the different types of fluids that are available,

While I have don't have a reference, I heard someone mention that the nano-sized particles of iron can be incorporated in an organic molecule -- vaguely similar to the iron atoms in hemoglobin (in red blood cells).
