“…15 In order to study the depoling mechanism, we investigated the domain stability of BS-xPT-PZN with tetragonal-structured composition x = 0.66 ͑BS-66PT-PZN͒ and rhombohedralstructured composition x = 0.54 ͑BS-54PT-PZN͒ at different annealing temperatures and poling fields. However, the thermal mechanism of the piezoelectricity is unclear.…”

Enhanced piezoelectric performance of (0.98-x)Bi(Sc3/4In1/4)O3-xPbTiO3-0.02Pb(Zn1/3Nb2/3)O3 ternary high temperature piezoelectric ceramicsThe structure, electrical properties, and depoling mechanism of the ͑0.95− x͒BiScO 3 − xPbTiO 3 − 0.05Pb͑Zn 1/3 Nb 2/3 ͒O 3 ͑BS-xPT-PZN, x = 0.54-0.70͒ compositions close to the morphotropic phase boundary ͑MPB͒ have been systematically investigated as a function of PbTiO 3 content ͑x͒. The phase approached from the rhombohedral toward the tetragonal phase when the PbTiO 3 contents increased. The composition with high PT content exhibited normal ferroelectric behavior while it showed a diffused phase transition characteristic as PT decreased. In the vicinity of the MPB, the ceramics showed enhanced piezoelectric, electromechanical, and ferroelectric properties with piezoelectric constant d 33 = 490 pC/ N, planar electromechanical coupling factors k p = 57.4%, remnant polarization P r = 40.1 C / cm 2 , and coercive field E c = 28.5 kV/ cm with a high transition temperature T m ϳ 417°C, respectively. The thermal depoling experiments of the polarization for samples with different phase structures were investigated and the possible depoling mechanism was discussed.

“…Law et al reported that the depolarization of lead zirconate titanate ͑PZT͒ resulted in a loss of piezoelectricity and a transformation of the domain state. 2 In an earlier work, Cook et al indicated that heating of poled ceramics below T C caused a change in the preferred domain orientation without affecting the piezoelectricity. 3 This unexpected behavior was explained by assuming that heating switches the domains back to the poled state, resulting in an increase in the preferred orientation of the ceramics.…”

Thermal effects on domain orientation in tetragonal lead zirconate titanate (PZT) and lead titanate (PT) have been investigated by using in situ x-ray diffraction with an area detector. In the case of a soft PZT, it is found that the texture parameter called multiples of a random distribution (MRD) initially increases with temperature up to approximately 100°C and then falls to unity at temperatures approaching the Curie temperature, whereas the MRD of hard PZT and PT initially undergoes a smaller increase or no change. The relationship between the mechanical strain energy and domain wall mobility with temperature is discussed.

“…The thermal depolarization is probably due to the relaxation and reorientation of polymer chains. The inorganic piezoelectric ceramics, such as PZT, also lose their piezoelectric property when annealed below the Curie point [53]. Since a nanogenerator is expected to stay in the environment for an extended period of time, the long-term thermal stability of its piezoelectric property must be considered to determine the operation temperature.…”

The desire for self-powered nanosystems and wearable devices has driven wide investigation of the sustainable energy source. Harvesting energy from the ambient environment with nanogenerators becomes a viable solution with the development of low-power electronics. Different devices can face dramatically different working conditions, which may seriously restrict the application of those nanogenerators. In this review article we describe the most recent progress in the study of the environmental effect on the nanogenerator. While a variety of nanogenerators have been developed using piezoelectric, triboelectric, pyroelectric and thermoelectric effects, the most studied piezoelectric nanogenerator and triboelectric nanogenerator will be discussed in more detail. This review emphasizes the important effect of the temperature, humidity, and water. The other effects, such as UV radiation or adsorption of gas or solid material, are also presented for certain nanogenerators. In the end we share our views of the future research directions and the remaining challenges in this field.
