“…The presented results reported a power generation of 244 mW (64% efficiency) under sinusoidal loads of 13 kN amplitude and 80 Hz frequency (equivalent to 100 km/h). Despite the considerable number of applications in the literature, EH remains an active and growing area of research [39,40]. Among others, open challenges include the development of new harvesting devices with higher output power, low-power electronics, more efficient energy collection and storage systems, and non-linear piezoelectric devices apt for broadband harvesting.…”

“…They have been widely used in MEMS/NEMS devices as micro/nano-sensors, actuators, and energy harvesters. [3][4][5] The reversible coupling between mechanical deformation and electric potential makes piezoelectrics desirable for these applications. Piezoelectric behavior comes with a special requirement known as a non-centrosymmetric crystal structure.…”

To accurately analyze the fracture behavior of piezoceramics at small length scales, flexoelectricity must be considered along with piezoelectricity. Due to its dependence on size, flexoelectricity predominates at the micro-and nano-length scales. Additionally, crack tips having the largest strain gradient state cause large flexoelectricity around them. Different approaches are employed in the past to model cracks computationally. However, extended isogeometric analysis (XIGA) is proven to be an accurate and efficient method. C 1 continuity requirements for modeling gradients in flexoelectricity are met by non-uniform rational B-splines (NURBS) basis functions used in XIGA. In this work, XIGA-based computational model is developed and implemented to study the fracture behavior of the piezoelectric-flexoelectric domain. An in-house MATLAB code is developed for the same. Several numerical examples are studied to ensure the efficacy and efficiency of the implemented model, and crack behavior is presented in the form of an electro-mechanical J-integral. The analysis is carried out to investigate how cracks behave for different flexoelectric coefficients under different electrical and mechanical loading combinations. J-integral is also analyzed against crack parameters such as crack orientation and length. It is observed that boundary loads and flexoelectric material constants significantly influence J-integral. Results also show a considerable amount of fracture toughening in the presence of flexoelectricity. The peak value of J-integral is found to be reduced with an increase in the flexoelectric coefficient. A significant reduction in J-integral, as much as 45%, is observed when the flexoelectric constant varied from 0.5 to 2 µCm −1 .

“…According to the principle of piezoelectricity, a potential difference is developed whenever the piezoelectric material experiences stress or mechanical pressure. Amongst the various mechanical stress sources, vibrations from human movements are used as the primary and spontaneous power source for PZT floor tiles, which convert them into useful energy [ 4 ].…”

This paper presents an experimental analysis of the optimization of PZT-based tiles for energy harvesting. The hardware (actual experiment), PZT-based tiles, were developed using 6 × 6 piezoelectric (PZT—lead zirconate titanate) sensors of 40 mm in diameter on a hard cardboard sheet (300 × 300 mm2). Our experimental analysis of the designed tiles obtained an optimized power of 3.626 mW (85 kg or 0.83 kN using 36 sensors) for one footstep and 0.9 mW for 30 footsteps at high tapping frequency. Theoretical analysis was conducted with software (Design-Expert) using the response surface methodology (RSM) for optimized PZT tiles, obtaining a power of 6784.155 mW at 150 kg or 1.47 kN weight using 34 sensors. This software helped to formulate the mathematical equation for the most suitable PZT tile model for power optimization. It used the quadratic model to provide adjusted and predicted R2 values of 0.9916 and 0.9650, respectively. The values were less than 0.2 apart, which indicates a high correlation between the actual and predicted values. The outcome of the various experiments can help with the selection of input factors for optimized power during pavement design.
