“…In second step, cobalt ferrite nanoparticles with different weight percentages (0, 2.5, 5, and 10%) were added to PVDF-TrFE to make nanocomposites. As shown in Figure 4H, an electrostatic spinning process was employed to make polyvinylidene difluoride matrix fiber membranes with modified lead zirconate titanate nanoparticles (PZT NPs) (Yuan et al, 2023). The inserted particles changed the distribution of polarized electric field, which helped to polarize PVDF.…”

Piezoelectric materials have become a key component in sensors and actuators in many industrial fields, such as energy harvesting devices, self-powered structures, biomedical devices, nondestructive testing, owing to the novel properties including high piezoelectric coefficient and electromechanical coupling factors. Piezoelectric thin films integrated on silicon substrates are widely investigated for their high performance and low manufacturing costs to meet the requirement of sensor networks in internet of things (IoT). The aim of this work is to clarify the application and design structure of various piezoelectric thin films types, synthesis methods, and device processes. Based on latest literature, the process of fabricating thin film sensors is outlined, followed by a concise overview of techniques used in microelectromechanical systems (MEMS) processing that can integrate more complex functions to obtain relevant information in surrounding environment. Additionally, by addressing piezoelectric thin films sensors as a cutting-edge technology with the ability to produce self-powered electronic devices, this work delivers incisive conclusions on all aspects of piezoelectric sensor related features. A greater understanding of piezoelectricity is necessary regarding the future development and industry challenges.

“…The enhanced strength and stiffness of the PVDF:PZT-N hybrid nanofibers could be attributed to the combined effect of the strong interface interaction of the PZT nanoparticles and Nafion with the PVDF polymer . Additionally, the excellent tensile strength of the hybrid nanofibers results from the improved dispersion of PZT within the PVDF:PZT-N matrix . The superior mechanical elastic characteristics of PVDF:PZT-N are considerable for flexible and stretchable materials, particularly in applications involving PENG and TENG devices that demand elastic materials.…”

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.

This study explored the impact of hot press parameters on PZT/PVDF composite films designed for force‐sensing applications. The systematic fraction (PZT/PVDF), pressure, temperature, and time during hot pressing processes are subject to variation during hot pressing processes. The focus is on the resulting composite film thickness and its subsequent influence on the piezoelectric properties, which are essential for the performance of force sensors. The present study investigates the characteristics and performance of PZT/PVDF composite films with fraction ratios 2/5, 5/5, and 7/3 and Hot Pressure (HP) 10, 40, and 60 MPa and temperature at 150°C for 2 h. The characterization of these films was conducted using X‐ray diffraction (XRD), Fourier‐transform infrared spectroscopy (FTIR), Atomic force microscopy (AFM), and scanning electron microscopy (SEM). The piezoelectric properties (d33 and d31 constant) were measured using impact and extraction tests to evaluate the performance of films to applied forces. The results show that the highest piezoelectric coefficients (d33 and d31) were determined to be 35.8 pC/N and 12.60 pC/N, with fraction ratios of 7/3 and 2/5. The study revealed a positive correlation between the PZT/PVDF ratio and sensitivity, indicating that an increase in the ratio leads to an increase in sensitivity. Conversely, a negative relationship was observed between the impact load and the sensor's sensitivity, suggesting that an increase in the impact load results in a sensitivity drop. The results of this work demonstrate the great potential of piezoelectric PZT/PVDF composite films in force sensors for small load applications.This article is protected by copyright.
