I want to know for a project for school if the value Electromechanical coupling coefficient of piezoelectric material will be the same in both directions? (from machanical to electric and from electric to mechanical)
So in formula from:
Em=Ee * K^2 and Ee=Em * K^2
and not something like:
Em=Ee * K1^2 and Ee=Em *K2^2
thanks in advance !
