To whom it may be concern,

I am interested in micro-actuator using Ni-Ti thin films(SMA, shape memory
alloy).
I have some data about the film in bulk state.
Would you let me know thermal expansion difference between bulk and SMA thin
film (2-micrometers)
including general tendency of thin film metals?

Is there any difference in thermal expansion coefficient between bulk and thin
film?


Waiting for your reply,
Best Regards.
