title: An analytical solution for the electromechanical coupling constant of an unloaded piezoelectric bimorph.
abstract: We present an analytical expression of the electromechanical coupling constant of a piezoelectric bimorph. A simplified impedance equation is presented that allows for the determination of the electromechanical coupling, flexural rigidity, and free permittivity of the bimorph.
