“…Generally, PZT has showed significantly higher electromechanical coupling factor and exceptionally good piezoelectric properties, resulting in greater conversion efficiency of mechanical stress into electrical current. Thus, the PVDF:PZT composite material can harness superior piezoelectric properties, thereby amplifying the voltage generated when subjected to mechanical deformation . The PVDF:PZT-N nanofiber-based device demonstrates an output voltage of 6 V in the triboelectric region and 9 V in the coupled triboelectric and piezoelectric regions.…”

The rapid advancement of nanocomposite materials for coupled triboelectric and piezoelectric nanogenerators (TENG-PENG) has attracted considerable attention due to efficient mechanical energy harvesting in portable and self-powered systems. However, challenges persist due to the nonuniform distribution of guest materials within nanocomposites, resulting in limited surface potential and polarization properties. Here, we demonstrated the incorporation of Nafion into poly(vinylidene fluoride):lead zirconium titanate (PVDF:PZT) hybrid nanofibers, substantially enhancing the β phase. The surface potential of PVDF:PZT increased to 86 mV, representing a 21% increase over untreated PVDF, while stimulated PVDF:PZT-N hybrid nanofibers show a notable boost of ∼175 mV, increasing to 146% compared to PVDF. The hybrid PVDF:PZT-N exhibits a storage modulus of ∼306 Pa and electrospun hybrid nanofibers displays an elastic limit of ∼1.48 MPa. Furthermore, the efficacy of the PVDF:PZT-N nanofibers is validated through a comparative analysis between engineered single-and double-dielectric layered TENG-PENG devices, producing maximum output currents and voltages of ∼7 μA and ∼40 V, respectively. These TENG-PENG devices have demonstrated their potential to illuminate multiple light-emitting diodes and digital LED display boards. Overall, the incorporation of Nafion into PVDF:PZT nanofibers significantly enhances the output performance of synergistically integrated PENG and TENG systems, offering promising advancements in mechanical energy harvesting and self-powered electronic devices.

“…PENG's performance largely relies on piezoelectric materials. In addition to ceramics [2], commonly adopted piezoelectric materials in microfabrication include the polyvinylidene fluoride (PVDF) [3], wurtzite phase zinc oxide (ZnO) [4][5][6][7], and barium titanate (BaTiO 3 ) [8], etc. The typical doping materials include the titanium dioxide (TiO 2 ) [9], graphene oxide (GO) [10], carbon nanotube (CNT) [11], and MXene [12], etc.…”

The burgeoning internet of things (IoTs) and artificial intelligence (AI) technologies have prospered a variety of emerging applications. Human-machine interfaces (HMIs), for instance, enables users with intuitive, efficient, and friendly way to interact with machines, capable of instant information acquisition, processing, communication, and feedback, etc. These features require ultra-compact and high-performance transducers, and therefore self-powered sensors have become the key underlying technology for HMI applications. This review focuses on the piezoelectric, triboelectric, and hybrid self-powered sensors with particular attention to their microstructures and fabrication methods, showing that both traditional microfabrication and emerging fabrication methods like three-dimensional (3D) printing, electrospinning, and braiding have contributed to the planar, array, porous, fabric, and composite type self-powered sensors. Moreover, the integration method of piezoelectric and triboelectric sensor arrays (TSAs) is investigated. The crosstalk issue is highlighted, i.e. the signal interference between adjacent sensing units, and current solutions such as array design optimization, signal processing improvement, and material innovation to reduce crosstalk sensitivity have been reviewed through specific examples. Three categories of HMI applications have been outlined, including intelligent interaction, robotics, and human monitoring, with detailed explanations of how the self-powered sensors support these HMI applications. Through discussion of challenges and prospects, it is proposed that further coordinating the design and fabrication of micro devices with HMIs will potentially boost the intelligent application with even higher level of diversification, convenience, and interconnectivity.

Piezoelectric composites have received widespread attentions in the fields of biomedicine and in vitro wearable devices due to their ability to convert mechanical forces into charge signals. The preparation of piezoelectric composites with complex structures through 3D printing technology can not only effectively improve their piezoelectric output, but also enable their customized therapeutic applications. This paper first introduces the types of piezoelectric composites and reviews the 3D printing technology commonly used in their preparation, analyzing the advantages and disadvantages of each 3D printing technology. Then, the state‐of‐the‐art of the biomedical applications of piezoelectric composites, including drug sustained‐release, wound healing promotion, bone tissue cells growth promoting, neurorehabilitation stimulating, ultrasonic diagnosis, and in vivo biosensing and in vitro wearable sensing, are emphasized. Finally, the main factors affecting the applications of 3D printed piezoelectric composites are outlooked, and an in‐depth discussion on the challenges toward 3D printed piezoelectric composites are analyzed. This review is believed to provide some fundamental knowledge of 3D printed piezoelectric composites.
