“…For these energy harvesting devices, some researchers adopted the addition of piezoelectric NPs to improve the output performance. Beigh et al used a dual transduction BaTiO 3 /SU-8 based nanocomposite as the active layer to recover the impact-induced losses during the energy harvesting process [51]. Karumuthil et al prepared a nanocomposite of ZnO nanorods, exfoliated graphene oxide and multiwalled carbon nanotubes (CNTs) dispersed in PDMS resin to simultaneously collect piezoelectric and triboelectric with high efficiency [52].…”

Due to the advantages of excellent output power, low cost and easily preparation, triboelectric nanogenerator is developing rapidly in the field of renewable energy. The output performance of triboelectric nanogenerator is largely dependent on the surface charge density, which is closely related to the ability of the tribo-material to gain or lose electrons. To obtain higher output power, numerous efforts have been done on material modifications of the friction layer and electrodes of triboelectric nanogenerator with additional fillers or molecular modifications. In this review, advanced materials for the preparation of triboelectric nanogenerator devices to achieve high output, humidity-resisting and wear-resisting performance are presented and the working mechanisms of performance optimisation are discussed. Moreover, natural materials, recyclable materials and non-conventional electrode materials are mentioned to inspire subsequent research on triboelectric nanogenerator.

“…Therefore, flexible PENGs fabricated using inorganic and organic materials with high durability is a promising field to explore. Polymers like PDMS, polyethylene terephthalate (PET), Polyvinylidene fluoride (PVDF), Hybrid BaTiO3/SU-8 Nanocomposite, (SU-8) piezoelectric (ZnO) nanocomposite , etc along with some piezoelectric materials have been used to fabricate flexible PENGs [6][7][8][9][10]. Among all PENGs, PDMS based hybrid composite films have gained attention due to their high flexibility, stretchability, biocompatibility, low surface energy and chemically inert property [11][12][13][14].…”

Since lead-based piezoelectric nanogenerators (PENGs) possess serious health risks, environmental problems, proper disposal issues, and biocompatibility concerns, this work presents the fabrication of a flexible piezoelectric nanogenerator utilizing lead-free orthorhombic AlFeO3 nanorods for biomechanical energy scavenging to sustainably power electronics. Hydrothermal technique is used to synthesize the AlFeO3 nanorods and the PENG was fabricated on Indium tin oxide (ITO) coated Polyethylene terephthalate (PET) flexible film with AlFeO3 nanorods interspersed in polydimethylsiloxane (PDMS). Transmission Electron Microscopy (TEM) proved that the AlFeO3 nanoparticles are of nanorods shape. Through X-Ray Diffraction (XRD), it is validated that AlFeO3 nanorods have orthorhombic phase and crystalline structure. A high piezoelectric charge coefficient (d33) of 400 pm V-1 is obtained from the Piezoelectric Force Microscopy (PFM) of AlFeO3 nanorods. With optimized concentration of AlFeO3 in the polymer matrix, an open circuit voltage (VOC) of 30.5 V, current density (JC) of 0.7888±0.0001 µA cm-2 and an instantaneous power density of 240.6 mW m-2 are obtained under the application of a force of 1.25 kgf. To investigate the nanogenerator's practical utility, the PENG is used for lighting multiple LEDs, charging of a capacitor and as a pedometer via biomechanical energy harvesting. Hence, it can be employed for developing various self-powered wearable electronics such as flexible skin, artificial cutaneous sensors, etc.

Triboelectric nanogenerators (TENGs) are crucial for applications such as smart sensors and bio-electronics. In the current work, we aimed for improved performance of TENGs with incorporation of BaTiO3 powder, which is known for its strong ferroelectric properties, combining it with epoxy resin to improve the flexibility of our devices. We observed that our TENGs can operate for over 24 000 cycles with no degradation of function. Additionally, we improved the electrical performance of the TENGs by incorporating various aluminum concentrations that change the electronic properties in the form of mixed epoxy resin, BaTiO3, and Al nanopowders. To identify the optimum conditions for the best performance, we analyzed the electrical characteristics and material properties by employing scanning electron microscopy, energy dispersive x-ray spectroscopy, and x-ray diffractometry characterization techniques. Our findings suggest that this innovative combination of materials and optimization techniques can significantly improve the performance of TENGs, making them ideal for practical applications in various fields, such as low-power electronics, environmental monitoring and healthcare. Moreover, these enhanced TENGs can serve as sustainable and dependable energy sources for various applications.
