We receive the parametric structural schematic diagram of the multilayer piezo actuator for nanomechanics in contrast to Cady and Mason's electrical equivalent circuits for the calculation of the piezo transmitter, the piezo receiver, and the vibration piezo motor {\ref [1 -12]}. The parametric structural schematic diagram of the multilayer electro magneto elastic actuator is obtained with the mechanical parameters of displacement and force {\ref [14 ?20]}.The piezo actuator use for actuation of mechanisms, systems, or management based on the piezo effect, and convert electrical signals into mechanical movement or force. The investigation of the static and dynamic characteristics of the multilayer piezo actuator is necessary for the calculation of nanomechatronics systems. We apply multilayer piezo actuator in nanotechnology for scanning tunneling microscopy and atomic force microscopy {\ref [6 ? 32]}. \section[{II. Parametric Structural Schematic Diagram}]{II.

We receive the structural diagram of the multilayer piezo actuator for the transverse, longitudinal, and shift piezo effects.\par From the general equation of electro magneto elasticity, the force that causes the deformation, the system of the equations for the equivalent quadripole of the multilayer actuator, and the forces on its faces, we obtain generalized structural-parametric model and generalized structural diagram of the multilayer electro magneto elastic actuator for the nanomechanics.\begin{figure}[htbp] \noindent\textbf{1}\includegraphics[]{image-2.png} \caption{\label{fig_0}Figure 1 :}\end{figure} \begin{figure}[htbp] \noindent\textbf{2}\includegraphics[]{image-3.png} \caption{\label{fig_1}Figure 2 :}\end{figure} \begin{figure}[htbp] \noindent\textbf{}\includegraphics[]{image-4.png} \caption{\label{fig_2}}\end{figure} \begin{figure}[htbp] \noindent\textbf{}\includegraphics[]{image-5.png} \caption{\label{fig_3}}\end{figure} \footnote{Multilayer Electro Magneto Elastic Actuator for Nanomechanics} \footnote{© 2019 Global Journals} \footnote{Year 2019 © 2019 Global JournalsC} \backmatter \begin{bibitemlist}{1} \bibitem[ IEEE/ASME Transactions on Mechatronics]{b4}\label{b4} \textit{}, 1109/TMCH.20. \textit{IEEE/ASME Transactions on Mechatronics} 15 (5) p. 770. \bibitem[S1028335808030063]{b9}\label{b9} \textit{}, / S1028335808030063 . \bibitem[S1068798x11090036]{b25}\label{b25} \textit{}, / S1068798x11090036 . \bibitem[Bartul et al.]{b34}\label{b34} \textit{}, Z Bartul , J Trenor , Nova Science .
