“…Other nanoparticles like carbon black [18,19], iron oxide nanoparticles [20], nickel powders [21] or graphite [22] have been used to improve the piezoresistive response of these composites, and even their mechanical performance. Strain sensing of cement composites has been applied to detect vehicles pressure in traffic monitoring [23], crack sensing and healing of concrete beams [24], or as sensor in testing of civil engineering structures [25].…”

“…Piezoelectric nanobeams have various practical applications in smart devices and systems due to their exceptional electromechanical coupling effect [1,2], such as nanotransducers, nanoresonators, nanosensors and nanogenerators [3][4][5][6]. It is thus essential to quantify and understand the vibration behaviors of piezoelectric nanobeams.…”

In this study, vibration characteristics of a piezoelectric nanobeam embedded in viscoelastic medium are investigated based on nonlocal Euler-Bernoulli beam theory. In doing this, the governing equations of motion and boundary conditions for vibration analysis are first derived by using Hamilton's principle, where nonlocal effect, piezoelectric effect, flexoelectric effect and viscoelastic medium are considered simultaneously. Subsequently, the transfer function method is employed to obtain the natural frequencies and corresponding mode shapes in closed form for the embedded piezoelectric nanobeam with arbitrary boundary conditions. The proposed mechanics model is validated by comparing the obtained results with those available in the literature, where good agreement is achieved. The effects of nonlocal parameter, boundary conditions, slenderness ratio, flexoelectric coefficient and viscoelastic medium on vibration responses are also examined carefully for the embedded nanobeam. The results demonstrate the efficiency and robustness of the developed model for vibration analysis of a complicated multi-physics system comprising piezoelectric nanobeam with flexoelectric effect, viscoelastic medium and electrical loadings.

The filling of thin-walled steel tubes with quartz sand can help to prevent the premature buckling of the steel tube at a low cost. During an impact, the internal stress of the quartz sand-filled steel tube column is subjected to not only axial force but also lateral confining force, resulting in complicated internal stress. A suitable sensor for monitoring the internal stress of such a structure under an impact is important for structural health monitoring. In this paper, piezoceramic Smart Aggregates (SAs) are embedded into a quartz Sand-Filled Steel Tube Column (SFSTC) to monitor the internal structural stress during impacts. The piezoceramic smart aggregates are first calibrated by an impact hammer. Tests are conducted to study the feasibility of monitoring the internal stress of a structure. The results reflect that the calibration value of the piezoceramic smart aggregate sensitivity test is in good agreement with the theoretical value, and the output voltage value of the piezoceramic smart aggregate has a good linear relationship with external forces. Impact tests are conducted on the sand-filled steel tube with embedded piezoceramic smart aggregates. By analyzing the output signal of the piezoceramic smart aggregates, the internal stress state of the structure can be obtained. Experimental results demonstrated that, under the action of impact loads, the piezoceramic smart aggregates monitor the compressive stress at different locations in the steel tube, which verifies the feasibility of using piezoceramic smart aggregate to monitor the internal stress of a structure.
