Really Strong Plastic

Electroactive Polymers (EAPs) have had relatively little exposure compared to other developments in the sceintific world. Basically they are malleable materials that respond to electrical stimilus in much the same way as muscles do. This referenced article discusses the challenge issued by a NASA engineer to anyone who could beat his EPA-based arm in an arm wrestling contest. Interesting background reading on the story and the technology. What is more interesting is the potential developments with EPAs. Imagine roll-up tables that can be made rigid by a single electical impulse and deactivated for easy fold-up and storage. source:
