Undecided. The audio at the end of Terminator might work pretty well, both for the crushing and the yelling.

I can see where a crunch sound might be too gruesome. Having Padme yell or simply say "ouch!" might be enough.

Natalie does say "You're breaking my heart" in Episode III. Does she say "hand" anywhere in the prequels or some other film?

You don't really need 'hand'....

Ani: (grabs her hand) Mechanical sounds, and a little crunching...

Padme: "Owwww.....Ani....You'r breaking my...."

Ani: (lets go of her hand) "...Sorry?"
