SUMMARY
The electromechanical coupling coefficient (K^2) of piezoelectric materials is consistent in both directions of energy conversion, meaning it remains the same when converting mechanical energy to electrical energy and vice versa. The formulas Em = Ee * K^2 and Ee = Em * K^2 confirm this relationship, indicating that K^2 is a constant ratio of electric to mechanical strain. This property is fundamental to the behavior of piezoelectric materials in various applications.
