“…They experience mechanical deformations when placed in an electric field, and become electrically polarized under mechanical loads and therefore, make them appropriate for a variety of electromechanical systems used for vibration and noise control [1][2][3], energy harvesting [4], cooling devices [5], telecommunication, and sensor networks [6]. With the development of the material technology, piezoelectric materials have been employed in micro/nano structures such as, micro/nano electromechanical systems (MEMS/NEMS) [7], nanoresonators [8], chemical sensors [9] and biosensors [10].…”

In this paper, thermoelectric-mechanical buckling behavior of the piezoelectric nanobeams is investigated based on the nonlocal theory and Euler-Bernoulli beam theory. The electric potential is assumed linear through the thickness of the nanobeam and the governing equations are derived by Hamilton's principle. The governing equations are solved analytically for different boundary conditions. The effects of the nonlocal parameter, temperature change, and external electric voltage on the critical buckling load of the piezoelectric nanobeams are discussed in detail. This study should be useful for the design of piezoelectric nanodevices.

“…When a very large number of sensors are dispersed in an environment, it is necessary that they are provided with a power supply of the longest possible life to limit maintenance, which is also impossible under certain conditions. The most commonly adopted solution is to draw from the source of mechanical energy, a priori infinite, induced by the vibrations of the immediate environment of the sensor (Nassit & Berbia 2015;Sborikas et al, 2016;Jandaghian et al, 2014). The conversion of the mechanical energy into electrical energy (Manbachi & Cobbold 2011; is carried out by an electromechanical generator.…”

The aim of this paper is to provide a theoretical analysis on the mechanical power of the mass spring's system. Some tests are conducted to experimentally evaluate the theoretical analysis and to investigate the mechanical energy ability of this concept. The authors suggest a system used for applications of energy harvesting from roads. The system is able to transform the kinetic energy produced by the passage of vehicles on the road for electrical energy based on the mass-spring using two technologies. The hybrid system has two goals. First, supply the entourage by a mechanism to produce significant electrical power used mainly for public lighting. A device is also provided for storing electrical energy for later use, for home lighting at night or in the case of bad weather. Second, the piezoelectric subsystem controls the spring's health through analyzing the amplitude and shape of the voltage generated by a piezoelectric material. Finally, an experimental validation of the designed smart speed bump is presented.

In this paper, we analytically study vibration of functionally graded piezoelectric (FGP) nanoplates based on the nonlocal strain gradient theory. The top and bottom surfaces of the nanoplate are made of PZT-5H and PZT-4, respectively. We employ Hamilton's principle and derive the governing differential equations. Then, we use Navier's solution to obtain the natural frequencies of the FGP nanoplate. In the first step, we compare our results with the obtained results for the piezoelectric nanoplates in the previous studies. In the second step, we neglect the piezoelectric effect and compare our results with those obtained for the functionally graded (FG) nanoplates. Finally, the effects of the FG power index, the nonlocal parameter, the aspect ratio, and the lengthto-thickness ratio, and the nanoplate shape on natural frequencies are investigated.
