Electromechanical coupling coefficient
- Electromechanical coupling coefficient
Electromechanical coupling coefficient is a numerical measure of the conversion efficiency between electrical and acoustic energy in piezoelectric materials.
Qualitatively the electromechancial coupling coefficent, k, can be determined as:
