In this reported work, the vibration response of a double-piezoelectric-nanoplate-system (DPNPS) under an external electric voltage is investigated. The two piezoelectric nanoplates are coupled by a polymer matrix. Small scale effects are taken into consideration using the non-local elasticity theory. Hamilton's principle is employed to derive the differential equations of motion. Explicit closed-form expressions are derived for the natural frequencies and critical electric voltages of the DPNPS. The numerical results are presented for both in-phase and out-of-phase vibrational modes. It is shown that the natural frequencies of the DPNPS are quite sensitive to the vibrational mode and non-local parameter. The present work is likely to prove very useful in the designing of micro-/nanodevices using smart nanocomposite.
