Abstract :
The constituent equations for piezoelectric bimorphs are written in terms of redefined extensive and intensive variables which makes it possible to write the bimorph matrix in numerical form. This numerical matrix is diagonalized to give the eigenvalues of bimorphs. The modal matrix is used to find the corresponding eigenstates. A physical interpretation of bimorph eigenstates is proposed. Two realizations of network representation are given for the admittance matrix. The eigenvalue matrix is inverted to give the impedance matrix. The network representation of the impedance matrix is given
