Traditional piezoelectric harvesters, such as cymbal and bridge structures, cannot be used inside tires due to their design limitations. The wider adoption of renewable energy sources into the energy system is increasing rapidly, reflecting a global attraction toward the utilization of sustainable power sources (Aljendy et al. in Int J Power Energy Convers 12(4): 314–337, 2021; Yesner et al. in Evaluation of a novel piezoelectric bridge transducer.

This study presents a novel one-end cap tire strain piezoelectric energy harvester (TSPEH) that can be used efficiently and reliably inside a tire. The interaction between the tire and energy harvester was analyzed using a decoupled modeling approach, which showed that stress concentration occurred along the edge of the end cap. The TSPEH generated a maximum voltage of 768 V under 2 MPa of load, resulting in an energy output of 32.645 J/rev under 1 MPa. The computational findings of this study were consistent with previous experimental investigations, confirming the reliability of the numerical simulations.

The flexible perovskite solar cell (FPSC), which capitalizes on the benefits of perovskite thin-film deposition and operates at low temperatures, is key to this transition. The FPSC is strategically important for large-scale deployment and mass manufacturing, especially when combined with the benefits of perovskite thin-film deposition under moderate thermodynamic conditions. Its versatility is demonstrated by the ease with which it may be folded, rolled, or coiled over flexible substrates, allowing for efficient transportation. Notably, FPSCs outperform traditional solar panels in terms of adaptability. FPSCs have several advantages over rigid substrates, including mobility, lightweight properties that help transportation, scalability via roll-to-roll (R2R) deposition, and incorporation into textiles and architecture. This in-depth examination dives into their fundamental design and various fabrication techniques, which include conducting substrates, absorber layers, coordinated charge movement, and conductive electrodes. This review evaluates critical FPSC fabrication techniques such as thermal evaporation, R2R approaches, slot die and spray deposition, blade coating, and spin coating.
