“…Also, the maximum tan δ is larger for PMN-PT-0.05BNZ than that of the un-doped composition. We presume that the loss peak and tan δ differences are due to the induced BNZ enhancing the dynamics of the local structure heterogeneity, and a similar phenomenon has been reported in other work on Sm modification [34,43,44]. The imaginary part of the dielectric permittivity (ε''/ε0) measured at the frequency range from 1 kHz to 30 kHz as a function of temperature are displayed in Fig.…”

High piezoelectric property and low strain hysteresis are both equally necessary for practical applications in precisely controlled piezoelectric devices and systems. Unlike most of the work reported in the literature to date where enhanced piezoelectric performance is typically accompanied by a large hysteresis in lead/lead-free based ceramics, in this work we report a reconstructed relaxor ferroelectric composition in 0.68Pb(Mg1/3Nb2/3)O3-0.32PbTiO3 ceramics through the introduction of (Bi0.5Na0.5)ZrO3 to simultaneously achieve a low strain hysteresis (~7.68%), superior piezoelectricity (~1,040 pC•N -1 ) and a electric induced strain of 0.175%. Our work not only paves the way to Journal of Advanced Ceramics https://mc03.manuscriptcentral.com/jacer 2 simultaneously large piezoelectricity and negligible strain hysteresis in ceramic systems, but also lays the foundation for further development of novel functional materials.

Ambient energy harvesting has great potential to contribute to sustainable development and address growing environmental challenges. Converting waste energy from energy-intensive processes and systems (e.g., combustion engines and furnaces) is crucial to reducing their environmental impact and achieving net-zero emissions. Compact energy harvesters will also be key to powering the exponentially growing smart devices ecosystem that is part of the Internet of Things, thus enabling futuristic applications that can improve our quality of life (e.g., smart homes, smart cities, smart manufacturing, and smart healthcare). To achieve these goals, innovative materials are needed to efficiently convert ambient energy into electricity through various physical mechanisms, such as the photovoltaic effect, thermoelectricity, piezoelectricity, triboelectricity, and electromagnetic power transfer. By bringing together the perspectives of experts in various types of energy harvesting materials, this Roadmap provides extensive insights into recent advances and present challenges in the field. Additionally, the Roadmap analyzes the key performance metrics of these technologies in relation to their ultimate energy conversion limits. Building on these insights, the Roadmap outlines promising directions for future research to fully harness the potential of energy harvesting materials for green energy anytime, anywhere.
