I like your idea.
My understanding is that Nitinol requires temperature change. What would cause the temperature change in your system?
A 1 W laser pen flash...
Hmmmm. Not sure about it but the laser is an interesting idea. Can we power it with a Joule thief so we use a little power as possible? I'm concerned about the laser not hitting all the nitinol evenly.
