“…Shindo et al 1 performed an experimental and analytical study on the static fatigue of the PZT ceramics under electromechanical loading, and showed that direct current (DC) electric fields can affect the fatigue life of the PZT ceramics. Narita et al 2 also studied the cyclic fatigue crack growth in single-edge precracked-beam (SEPB) PZT specimens under sinusoidal mechanical load and DC electric fields, and discussed the effect of applied electric fields on the crack * Corresponding author.

“…4 one obtains the T-stress as a function of the applied electric field. Superposition of this result with the mechanically induced T-stress (12), as anticipated in (11), would yield the variation of T-stress under coupled electromechanical loading. The final results, in conjunction with the experimental data reported in Figure 2, are plotted in Figure 6.…”

“…In these services, ferroelectrics have to bear external electrical and/or mechanical loadings in a cyclic or a static form. Crack growth in ferroelectrics driven by electrical or mechanical, or electromechanical loading has been an important topic in the past two decades [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. For details, one can refer to the monograph by Yang [15] and the review by Schneider [16].…”

Experimental results indicate three regimes for cracking in a ferroelectric double cantilever beam (DCB) under combined electromechanical loading. In the loading, the maximum amplitude of the applied electric field reaches almost twice the coercive field of ferroelectrics. Thus, the model of small scale domain switching is not applicable any more, which is dictated only by the singular term of the crack tip field. In the DCB test, a large or global scale domain switching takes place instead, which is driven jointly by both the singular and non-singular terms of the crack-tip electric field. Combining a full field solution with an energy based switching criterion, we obtain the switching zone by the large scale model around the tip of a stationary impermeable crack. It is observed that the switching zone by the large scale model is significantly different from that by the small scale model. According to the large scale switching zone, the switch-induced stress intensity factor (SIF) and the transverse stress (T-stress) are evaluated numerically. Via the SIF and T-stress induced by the combined loading and corresponding criteria, we address the crack initiation and crack growth stability simultaneously. The two theoretical predictions roughly coincide with the experimental observations. ferroelectric ceramics, large scale domain switching, electromechanical loading, crack initiation, crack growth stability, stress intensity factor, transverse stress

In the coming era of the internet of things (IoT), wireless sensor networks that monitor, detect, and gather data will play a crucial role in advancements in public safety, human healthcare, industrial automation, and energy management. Batteries are currently the power source of choice for operating wireless network devices due to their ease of installation; however, they require periodic replacement due to capacity limitations. Within the scope of the IoT, battery maintenance of the trillion sensor nodes that may be implemented will be practically infeasible from environmental, resource, and labor cost perspectives. In considering individual self-powered sensor nodes, the idea of harvesting energy from ambient vibrations, heat, and electromagnetic waves has recently triggered noticeable research interest in the academic community. This paper gives an overview of energy harvesting materials and systems. Three main categories are presented: piezoelectric ceramics/polymers, magnetostrictive alloys, and magnetoelectric (ME) multiferroic composites. State-of-the-art harvesting materials and structures are presented with a focus on characterization, fabrication, modeling and simulation, and durability and reliability. Some perspectives and challenges for the future development of energy harvesting materials are also highlighted.
