Magnetic Metal Foam Shape Shifter

Posted January 13, 2008 8:34 AM

Researchers at Boise State (Idaho) and Northwestern (Chicago) developed magnetic shape-memory foam from a nickel-manganese-gallium alloy. The foam's metal grain deforms up to 10% under a magnetic field. The material retains the resulting shape when the field is removed, but returns to its original shape if the magnetic field is rotated 90 degrees. What applications can you envision?

The preceding article is a "sneak peek" from Metals & Alloys, a newsletter from GlobalSpec. To stay up-to-date and informed on industry trends, products, and technologies, subscribe to Metals & Alloys today.

Implantable pumps for medicinals (insulin, steroids, antibiotics, hormones, etc.); possibly even an artificial heart or kidney if the volume can be increased sufficiently.

For some reason this made me think about a material that can actually interact with ionic gases in the air in such a way that the material becomes suspended in air..as in "alien technology"...ET all all that hubba bubba...think about it...hehehe

Is it possible that is the reason many UFOs have been reported to change shape..kinda like a water balloon does when tossed..is because maybe the shape changing is the actually the crafts metallic outer shell interacting with the ion gases in the air rendering the craft weightless.

I don't know about the "weightless" part, but it sounds like it could be the basis for a propusion system...hmmm. Nice choice in avatars, by the way, my compliments!

Looks like it could have some applications in PLC systems. Form it into a rod and see what happens.
