Is there a way to make a Electroactive material at home? Answered

 What I am looking for is something that acts like a muscle. The material contracts when electricity is applied to it.  Any ideas?

Bimetallic strips buckle/contract as they heat up, and realign as they cool. You might get it to work depending on what kind of voltage you're working with, and how fast you want the contraction to occur. You can find them in many household objects, like old thermostats, some fuses, and the bulbs used to make incandescent christmas lights blink.

There is a link at www.sri.com (Stanford Research Institute) on electroactive polymers (EAP). it was spun off and is now part of Bayer. Evaluation kits and more information are available from this manufacturer. Have an idea for a robot using this technology. Might have it done by the end of the year.

Nitinol is one of the more popular "electric muscles", but I don't think it's something that most DIYers can make.

It does not have to be metal material it could be something more like a soft plastic or silicon.

.  I'm stumped. :(
.  If I weren't so lazy, I'd start looking here.

Nice,  But i was looking for something that, well ill give a example.  lets say this material  was in the shape of a sphere you apply electricity the sphere shrinks or contracts.

A solenoid.  Fine threads tend to do the opposite-straiten out when charged.

Not a lot of options for mechanical muscle tissue : (
