I need something gain in-plane vibration and the amplitude of several micrometers. I heard that piezoelectric ceramic transducers are suitable,but it may add mass to the metal plate. i don't konw if magnetostrictive transducers can do this.
To generate in-plane vibration, you can use shear piezoelectric elements.
For example, PIC255 elements from PI Ceramic are suitable to generate shear motion.
You could obtain some displacement in the out-of-plane direction, but it should be negligeable compared to the in-plane one.
You may use also electromagnetic non contact excitation of a metal sample by a coil (for example, from speaker) placed at a short distance (less than 1 mm) of it.
Is it a crazy idea of using parametric excitation for EMATs? It is working in a hydro-acoustic. Thank you.
is there any literature on in-plane vibration? thin rectangle or circular plate is OK, all edges are clamped.
I would like to know the theory about the in-plane vibration of rectangle plate with the condition of CFFF(one edge clamped) and CCCC(all edges clamped).
it would be better if there is any article on numerical simulation. and i did some research on rectangle plate modal anaysis by ANSYS, if the plate is one edge clamped, it is easy to see if the mode is in-plane vibration, but i don't konw how to decide it when all edges clamped.

You can use a PVDF or PVDF-TrFE film as your piezoelectric material. They are frequently laminated to guitars and violins as music pickups. And they are very light.
