“…The harvester used in this work was made of piezoelectric aluminum nitride on a flexible substrate of polyimide (commercial Kapton). Theoretical models showed that harvester efficiency could experience a drop with temperature due to thermal stresses [35]. Noteworthy, no creeps in the aluminum nitride piezoelectric layer were observed with temperature, suggesting the harvesting device could withstand the temperature range measured.…”

“…The calculation of the average gas speed starting from the measured mass flow rate has been performed using Equation (8). As described in previous work [34,35], the main component of the gas exhaust as it is in the air is N 2 . When considering the gas properties, neglecting the combustion products the error is typically not higher than 2%, therefore we have used air density when needed for the gas exhaust.…”

The exhaust system of the light-duty diesel engine has been evaluated as a potential environment for a mechanical energy recovery system for powering an IoT (Internet of Things) remote sensor. Temperature, pressure, gas speed, mass flow rate have been measured in order to characterize the exhaust gas. At any engine point explored, thermal energy is by far the most dominant portion of the exhaust energy, followed by the pressure energy and lastly kinetic energy is the smallest fraction of the exhaust energy. A piezoelectric flexible device has been tested as a possible candidate as an energy harvester converting the kinetic energy of the exhaust gas flow, with a promising amount of electrical energy generated in the order of microjoules for an urban or extra-urban circuit.

“…Temperature variations in the actual service environment can affect the performance of the probe. Previous studies have demonstrated that temperature variations affect the performance of piezoelectric devices, triggering phenomena such as impedance value change [59], peak frequency shift [60], and even loss of operational performance. Therefore, it is necessary for the proposed corrosion probes based on EMI technology to consider the effect of temperature variation in the actual service environment.…”

Rod-type metal corrosion probes based on electromechanical impedance (EMI) technique can quantitatively assess the amount of corrosion, which have a promising application in pipeline corrosion monitoring and have received more and more attention. In the design of piezoelectric smart devices, electrical series and parallel connections are very important and effective adjust method to improve the device performance, but it is yet to be used in the probe design. In this work, a kind of novel metal corrosion probe with two piezoelectric elements in series and parallel connections was proposed, and its performance was investigated comprehensively by combining theoretical analysis with experiment research. Theoretical models of the proposed probe in the longitudinal vibration mode for both series and parallel connections were established, and verified by the experimental results. Influences of the thicknesses of piezoelectric layer and ceramic layer on the probe performance were analyzed. Artificial quantitative corrosion tests and accelerated corrosion tests were designed to evaluate the quantitative corrosion monitoring capacity. Temperature sensitivity tests were conducted to study the temperature dependence. The wireless impedance measurement was performed to confirm the online monitoring ability. Comparisons for the probe performance between the series and parallel connections were also presented. This work provided a comprehensive understanding for this kind of novel probe, which is beneficial to develop low-cost, high-precision, high-stability pipeline corrosion real-time monitoring technology.

“…VEH technologies include a variety of transducers and scales, including macroscopic or mesoscale electromagnetic [8,9,10,11] and piezoelectric [12,13,14,15] generators to MEMS-scale electrostatic [16] and piezoelectric [17,18,19] harvesters. Research efforts in the VEH field include attempts to increase the operational bandwidth [20,21], operate at low frequency [22] or high temperature [23], improved electronic power conditioning efficiency [24,25] or mechanical efficiency [26,27]. In relation to the integration with composite materials, piezoelectric films are particularly suitable due to the thin profile and manufacturing compatibility [28,29].…”

This paper presents a finite element (FE) model developed using commercial FE software COMSOL to simulate the multiphysical process of pieozoelectric vibration energy harvesting (PVEH), involving the dynamic mechanical and electrical behaviours of piezoelectric macro fibre composite (MFC) on carbon fibre composite structures. The integration of MFC enables energy harvesting, sensing and actuation capabilities, with applications found in aerospace, automotive and renewable energy. There is an existing gap in the literature on modelling the dynamic response of PVEH in relation to real-world vibration data. Most simulations were either semi-analytical MATLAB models that are geometry unspecific, or basic FE simulations limited to sinusoidal analysis. However, the use of representative environment vibration data is crucial to predict practical behaviour for industrial development. Piezoelectric device physics involving solid mechanics and electrostatics were combined with electrical circuit defined in this FE model. The structure was dynamically excited by interpolated vibration data files, while orthotropic material properties for MFC and carbon fibre composite were individually defined for accuracy. The simulation results were validated by experiments with <10% deviation, providing confidence for the proposed multiphysical FE model to design and optimise PVEH smart composite structures.
