One of the key challenges in the development of high‐temperature energy harvesting (HTEH) technology is to clarify the relationship between temperature‐dependent material parameters and device power generation capabilities. However, at present, the research on temperature stability of piezoceramics mainly relies on thermal annealing technology, which cannot follow the actual temperature dependence of the piezoelectricity, and it is even more difficult to predict the temperature stability of HTEH. To shed light on this field, here, (1−x)BiScO3–xPbTiO3 system was chosen for building HTEH material, and the temperature‐dependent electrical parameters, such as d33, εr, and g33, have been measured by multiple in situ techniques. It was found that the synergistic effect of d33 and εr with temperature helps to obtain a stable g33 value in a wide temperature range. Moreover, in the mode of the cantilever‐type energy harvester, a stable output voltage was obtained at x = 0.64 harvester with <20% change over a broad temperature range of 100‐250°C, and it was verified that the temperature stability of g33 is crucial to the operation stability of HTEH devices.

Summary Energy harvesting technologies are growing rapidly in recent years because of limitation by energy storage and wired power supply. Vibration energy is abundant in the atmosphere and has the potential to be harvested by different mechanisms, mainly through piezoelectric and electromagnetic means. Various architectural structures were also designed for several operating conditions, namely, resonance frequency and range thereof, acceleration, and energy extraction from several motions. The advantages and disadvantages were elaborated on, and improvements on ideas from current research were discussed in this review.

Flexible polyvinylidene fluoride/(Na 0.5 K 0.5 )NbO 3 (PVDF/NKN) composite harvester was first characterized at high temperature. The origin of high flexibility is the unique structure assembled by alternately stacking four-sheets and three-fabrics (4-3 harvester). The 4-3 harvester was fabricated by uniformly dispersing piezoelectric NKN particles within a PVDF-sheet and a PVDF-fabric layer. Electric power-output of the 4-3 harvester was measured by using a custom-designed apparatus in the temperature range from 25 to 150°C and was compared with that of PVDF/BaTiO 3 (BT) harvester. The PVDF/NKN 4-3 harvesters and PVDF/BT 4-3 harvesters showed significantly different temperature dependences in the temperature range from 25 to 150°C. Electric power-output obtained at 25°C by applying an oscillation at 75 Hz in the thickness direction for the PVDF/ NKN 4-3 harvesters and PVDF/BT 4-3 harvesters were 5.7 and 3.5 nW/cm 2 per an amplitude, respectively. In particular, at temperature above 130°C, the PVDF/NKN 4-3 harvester showed a stable output performance from 3.3 to 3.8 nW/cm 2 , whereas the PVDF/BT 4-3 harvester demonstrated no electric power-output. Thus, the harvester composed of high T C piezoelectric particles such as NKN is suitable as a vibration energy harvester operated under high-temperature environment.
