“…When the applied force 1 N < F < 9 N, the voltage sensitivity can reach to 1.23 V N −1 and the current sensitivity of the sensors can reach to 41.0 nA N −1 . This result is superior to the sensors prepared by PVDF [49], P (VDF-TrFE) [32], BZT-BCT/P (VDF-TrFE) composite film [50] and is comparable to the triboelectric nanogenerators [2,51]. When the applied force 10 N < F < 55 N, the sensitivity of the sensors decreases to 0.102 V N −1 and 3.31 nA N −1 , respectively.…”

“…Inorganic piezoelectric perovskite materials and piezoelectric polymers have been widely utilized in the fabrication of piezoelectric sensors. Piezoelectric polymers, such as poly(vinylidene fluoride) (PVDF) [31] and poly(vinylidene fluoride-trifluoroethylene) (P (VDF-TrFE)) [32], have the intrinsic flexibility and biocompatibility. However, the output performance of nanogenerators based on piezoelectric polymers are restricted by the low piezoelectric coefficient.…”

“…Consequently, lead-free inorganic piezoelectric materials with outstanding performance have long been pursued. For instance, Ba 0.85 Ca 0.15 Zr 0.10 Ti 0.90 O 3 [ 33 ], BiFeO 3 [ 34 ] and (K, Na)NbO 3 -based [ 35 – 37 ] materials were reported to fabricate piezoelectric nanogenerators for energy harvesting and human motion sensing. Recently, it is found that stannum-doped BaTiO 3 (BTS) ferroelectric ceramics have the highest piezoelectric coefficient ( d 33 ) in lead-free piezoceramics with a low Curie temperature ( T c ) of ~ 40 °C[ 38 ].…”

For traditional piezoelectric sensors based on poled ceramics, a low curie temperature (Tc) is a fatal flaw due to the depolarization phenomenon. However, in this study, we find the low Tc would be a benefit for flexible piezoelectric sensors because small alterations of force trigger large changes in polarization. BaTi0.88Sn0.12O3 (BTS) with high piezoelectric coefficient and low Tc close to human body temperature is taken as an example for materials of this kind. Continuous piezoelectric BTS films were deposited on the flexible glass fiber fabrics (GFF), self-powered sensors based on the ultra-thin, superflexible, and polarization-free BTS-GFF/PVDF composite piezoelectric films are used for human motion sensing. In the low force region (1–9 N), the sensors have the outstanding performance with voltage sensitivity of 1.23 V N−1 and current sensitivity of 41.0 nA N−1. The BTS-GFF/PVDF sensors can be used to detect the tiny forces of falling water drops, finger joint motion, tiny surface deformation, and fatigue driving with high sensitivity. This work provides a new paradigm for the preparation of superflexible, highly sensitive and wearable self-powered piezoelectric sensors, and this kind of sensors will have a broad application prospect in the fields of medical rehabilitation, human motion monitoring, and intelligent robot.

“…Nafari et al [37] characterized the performance of nanocomposite PEHs made of a mixture of PDMS and PTO nanowires using FE simulations and experimental tests. Another lead-free and flexible nanogenerator film was proposed in the work of Hanani et al [38] where they fabricated such films using a mixture of piezoelectric BCZT nanopowder, polydopamine, and polylactic acid. Wasim et al [39] managed to grow ZnO nanorods on the faces of aluminum sheets and studied the electromechanical behavior of the developed nanogenerator.…”

Sweeping developments in microelectromechanical systems and low power electronics have pushed the need for piezoelectric energy harvesters (PEHs).Increasing environmental and biocompatibility issues have drawn interest in lead-free piezoelectric materials. In this paper, cantilever-type PEHs at centimeter scale have been proposed to harvest the energies of low-frequency vibrations caused by a human's movements. The proposed PEHs are made of a

“…Many nanogenerators have been fashioned after, including piezoelectric NGs (PENG), pyroelectric NGs (PyENG), triboelectric NGs (TENG), and photovoltaics (PVC) [26][27][28][29]. Piezoelectric and triboelectric NGs transform mechanical stress forces and/or energies from wind/airflow, water waves, human motions, biomechanical energies, etc., to electrical energy, accompanied by changing polarization degrees in ferroelectrics [30][31][32][33][34][35]. Pyroelectric NGs works by temperature variations from industrial heat wastes, radiations from the sun, etc.…”

Innovations in nanogenerator technology foster pervading self-power devices for human use, environmental surveillance, energy transfiguration, intelligent energy storage systems, and wireless networks. Energy harvesting from ubiquitous ambient mechanical, thermal, and solar energies by nanogenerators is the hotspot of the modern electronics research era. Ferroelectric materials, which show spontaneous polarization, are reversible when exposed to the external electric field, and are responsive to external stimuli of strain, heat, and light are promising for modeling nanogenerators. This review demonstrates ferroelectric material-based nanogenerators, practicing the discrete and coupled pyroelectric, piezoelectric, triboelectric, and ferroelectric photovoltaic effects. Their working mechanisms and way of optimizing their performances, exercising the conjunction of effects in a standalone device, and multi-effects coupled nanogenerators are greatly versatile and reliable and encourage resolution in the energy crisis. Additionally, the expectancy of productive lines of future ensuing and propitious application domains are listed.
