heat could generate the needed engergy to contract muscle wires, opening pores in the banket which would allow air flow to cool you. As the air got cooler, less energy would be directed into the wires. Other muscle wires could activate when it gets cold (batteries turned on by lack of heat?) and close
the pores tighter, also generating some heat and trapping it all inside.

You wouldn't really need batteries; nitinol can be
formulated for a transition temperature anywhere in a
very wide range, definitely wider than the average bed
blanket will experience. |

But would this work for more than one person under the covers? Also, what happens when the blanket gets kicked off the bed and the dog claims it? |
|

The problem I see is: How comfortable would a blanket with wires in it be? |

Chain mail is very comfortable, so wires don't necessarily have to be a bad thing. |

You'd end up with a funny grid pattern over your skin if you lay on chain mail. |

I've heard of bed head. Would mail give you chain brain? |
