There’s a further discussion here: http://arduino.cc/forum/index.php/topic,16201.0.html

1 SMA is using around 200mA, if i use 22 SMA in arduino board, can arduino able to control it?

This is awesome. This reminds me of a Jimmy Neutron episode where he was able to make his pants self fold. It would be awesome if we could do something like this. How much flexinol do you think it would need to accomplish something like folding a shirt? Oh, but now I realize that the current might burn the tissue. Well, nevermind.. Still, great work on the “living papers”, the videos are great!

Thanks again~ I might contact you again for more advice!!!

As for sourcing, the people at dynalloy (who wire) are really nice and might be able to ship internationally: http://dynalloy.com/

It doesn’t burn out as easily and moves pretty quickly– the wires contract when current runs through but they return to their natural shape through ambient cooling (which takes longer for thicker wires). And you could definitely power multiple pieces at the same time using one power source, but it does require a beefier source. In this case a 5v wall power supply would work better than a battery. However, if you’re just starting out I recommend making a single piece first and seeing how that goes.
