Summary: Nowadays, researchers are focused on developing smart materials that can respond to different stimuli to generate energy output. This paper investigates the pyroelectric energy harvesting capabilities of smart terpolymer poly(vinylidene-fluoride-trifluoroethylene-chlorotrifluoroethylene) [PVDF-TrFE-CTFE]-based nanocomposites. Sodium niobate (NaNbO3) is used as a filler and the Sol-gel method is employed to synthesize the NaNbO3 nanoparticles. The results show that adding NaNbO3 significantly enhances the energy harvesting density of the nanocomposites, making them promising materials for thermally stable energy harvesting systems design.

Summary: In this study, (1-x)Bi0.5Na0.5TiO3-xBaNi0.5Nb0.5O3 (BNT-xBNN, x = 0, 0.02, 0.03, 0.04 mol) lead-free ceramics were prepared, and the addition of BaNi0.5Nb0.5O3 improved the lattice cell expansion and decreased the O-B-O bond angles, resulting in micron-sized grains (3.25-6.15 mu m) with good ferroelectric performance (Pr = 42 mu C/cm2, Ps = 47 mu C/cm2). The permittivity (epsilon r) of pristine samples increased from 439 to 723 as the BNN content increased to 0.03 mol. As a result, an enhanced room temperature pyroelectric coefficient of 7.91 x 10-4 C m-2 K-1 with a high depolarization temperature of about 150 degrees C was achieved in BNT-xBNN with x = 0.03 mol, which correspondingly generated an energy density of 22.3 mu J/cm3 with a 90 M omega load. This work contributes to the development of practical applications in pyroelectric properties for energy harvesting.

Summary: A novel thermo-magneto-pyroelectric energy generator (TMPyEG) was developed to continuously harvest waste heat and convert it into electric energy without the need for complicated electric bias fields. By utilizing second-order magnetic phase transition, displacement reciprocation was achieved without intervention, and the energy gaps between pyroelectric energy outputs were mitigated by incorporating piezoelectric material. Notably, the generated energy from pyroelectric conversion in TMPyEG outperformed that of thermoelectric generators under similar thermal conditions.

Summary: This study investigates the performance of a pyroelectric energy harvester (PEH) used as a dielectric substrate in power electronic modules, and develops a comprehensive analytical model in MATLAB software to validate the theoretical results with experimental data. The results show that the pyroelectric substrate can harvest an average power of 50 μW/cm2. It is also found that input heat rate frequency higher than 2 Hz has no significant impact on power generation by the pyroelectric module, and convective cooling density with low heat transfer coefficients can increase power generation.

Summary: Identifying reliable and sustainable sources of electricity is a major challenge, as most energy-generation mechanisms produce waste heat. Over 60% of primary energy is wasted as heat each year. Efforts are being made to convert this waste heat into usable electrical energy using diverse energy conversion materials. This review focuses on three energy conversion mechanisms (pyroelectric, thermomagnetic, and thermogalvanic generators) and discusses their theoretical basis, critical parameters, and current status. The challenges and opportunities in low-grade waste-heat recovery are explored in terms of material science and structural design. This review provides an overview of thermal-energy-harvesting research progress, future challenges, and opportunities.
