Does anyone has an idea on how to establish an electromagbetic control of a flexible and thin polymer (5-10 um thick)?
I think shrinking an electromagnet down to this size might not work. Is there a simplier way? would it work to have a coil on the “controller” and simply a magnetizable metal on the “probe that i want to move”? is there a limitation of size/dimensions this will work?
Thanks!
What parameter of the polymer are you interested in ?
Is it its complex permittivity ?
If your answer is yes then I can say that the complex permittivity
of such polymer is mesurable at microwave frequencies with ucertainties that are the order of relative
uncertainty of its thickness.
What kind of control do you want to have?
Simplest way is to put magnetic material in the polymer and control that from outside using magnet (something like this https://www.nature.com/articles/nmat3090).
