“…However, the authors used polycrystalline SbSI rods fabricated by solid-state reaction with micrometric size, but the general pattern is convergent. Similar studies have been performed in past years for sensors based on ZnO nanorods [ 83 , 84 , 85 ], laminated PZT thin films [ 86 ], Bi 4 Ti 3 O 12 nanoparticles [ 87 ], Si/SiO 2 nanowires [ 88 ], and BN nanotubes [ 89 ] which show that bending or compressive stress is more favorable than the tensile one.…”

“…As described above, features of epoxy/SbSI nanocomposite allow for its application not only as a strain sensor but also in smart sensing [ 26 , 87 , 88 , 89 , 90 ] and energy harvesting [ 9 , 36 , 37 , 76 ] applications, due to the extraordinary piezoelectric constant of SbSI [ 13 , 14 ]. Moreover, the usage of the epoxy matrix allows for obtaining almost all possible shapes of the nanocomposite, which due to its easy formability, is typical for them.…”

In this paper, the performance of epoxy/SbSI nanocomposite under tensile stress was investigated. X-ray diffraction studies show the main stress mode has shear nature in the case of elastic deformation, while a combination of shear and tensile stress during plastic deformation caused lattice deformation of SbSI and shift of sulfur atoms along the c axis of the unit cell. Apart from that, the piezoelectric signals were recorded during tensile tests. Epoxy/SbSI nanocomposite responded to the applied tensile stress by generating a piezoelectric current with a relatively high value. The measured piezoelectric peak-to-peak current is relatively high (Ip-p = 1 pA) in comparison to the current flowing through the sample (8.16 pA) under an applied voltage of 100 V. The current level is independent of the deformation speed rate in contradistinction to complex stress states. The signal comes from the whole volume of the sample between electrodes and is generated by shear stress.

Piezoelectric Materials for Energy Harvesting and Sensing Applications: Roadmap for Future Smart Materials

Piezoelectric materials are widely referred to as "smart" materials because they can transduce mechanical pressure acting on them to electrical signals and vice versa. They are extensively utilized in harvesting mechanical energy from vibrations, human motion, mechanical loads, etc., and converting them into electrical energy for low power devices. Piezoelectric transduction offers high scalability, simple device designs, and high-power densities compared to electro-magnetic/static and triboelectric transducers. This review aims to give a holistic overview of recent developments in piezoelectric nanostructured materials, polymers, polymer nanocomposites, and piezoelectric films for implementation in energy harvesting. The progress in fabrication techniques, morphology, piezoelectric properties, energy harvesting performance, and underpinning fundamental mechanisms for each class of materials, including polymer nanocomposites using conducting, non-conducting, and hybrid fillers are discussed. The emergent application horizon of piezoelectric energy harvesters particularly for wireless devices and self-powered sensors is highlighted, and the current challenges and future prospects are critically discussed.

“…So far, studies on the PENG device have boomed, using some excellent piezoelectric materials. The notable piezoelectric ceramics Pb x Zr 1– x TiO 3 , BaTiO 3 (BT), BiFeO 3 , and Bi 4 Ti 3 O 12 have a deserved reputation for energy harvesting because of their relatively mature synthesis process and superior piezoelectric coefficients, but their high brittleness limits applications and service life. , An intuitive and logical approach is to develop flexible composite materials with ceramic nanoparticles dispersed in a polymer matrix. , For instance, a (K, Na)NbO 3 –LiNbO 3 (KNLN) PENG device was constructed using intrinsically excellent piezoelectric KNLN nanoparticles and copper nanorods . It not only produces a large output of 12 V and 1.2 μA power generation but also presents excellent durability and stability.…”

The development of a flexible wearable piezoelectric power device has recently caught extensive attention, especially in making inorganic piezoelectric ceramics into polymers from a composite with excellent piezoelectric response. As inorganic piezoelectric fillers, an oriented polycrystal can improve the mechanical energy efficiency of piezoelectric nanogenerators. Herein, the two-dimensional BaTiO 3 -oriented polycrystals are prepared via a two-step hydrothermal process based on a topochemical conversion mechanism. Additionally, a high-performance piezoelectric nanogenerator was successfully fabricated using the polydimethylsiloxane (PDMS) polymer and BaTiO 3oriented polycrystals. The flexible piezoelectric nanogenerator with 30 wt % BaTiO 3 exhibited optimal piezoelectric performance, with an output opencircuit voltage of 13.0 V and a short-circuit current of 200 nA under a periodic mechanical bend−release mode. More importantly, an effective power of approximately 2.6 μW was achieved at a low load resistance of 35 MΩ, suggesting a large potential for applications of electronic skins and self-powered devices. The device efficiently harvests biomechanical energy from human activities and exhibits stable output voltage and current of approximately 8 V and 150 nA, respectfully, demonstrating great promise as a wearable energy harvester. This work demonstrates that oriented nanocrystals in combination with a polymer matrix can lead to the design of high-efficiency piezoelectric nanogenerators that are particularly useful in artificial intelligence, soft robotics, and biomedical devices.
