The benefits of combining 1D and 3D nanofillers in a piezocomposite nanogenerator for biomechanical energy harvesting

Abstract

Mechanical energy harvesting using piezoelectric nanogenerators (PNGs) offer an attractive solution for driving low-power portable devices and self-powered electronic systems. Here, we designed an eco-friendly and flexible piezocomposite nanogenerator (c-PNG)...

Inorganic ferroelectric thin films and their composites for flexible electronic and energy device applications: current progress and perspectives

“…Another study by the same group reported a composite thin-film-based PENG composed of HZTO-NW and BCZT as the fillers and PLA as the polymer matrix. 67 A finger touch on the PENG produced an output voltage of 11.5 V, output current of 0.6 mA, and a power density of 9200 mW cm À3 .…”

Alternatives to Fluoropolymers for Motion‐Based Energy Harvesting: Perspectives on Piezoelectricity, Triboelectricity, Ferroelectrets, and Flexoelectricity

“…[48,70] To control or manipulate this homogeneity of additives, researchers have studied the introduction of additives with different dimensionalities into polymer matrices. Hanani et al [71] have demonstrated that the co-addition of both 1D and 3D additives into a polylactic acid matrix led to a significant improvement compared to either 1D or 3D additive individually. The nature of additives and filler matrix are blurred when a complete piezoceramic foam is embedded in a polymer mesh, as described by Zhang et al [72] and Zhang et al [73] These porous systems also can create ferroelectrets giving rise to further enhanced electromechanical response, which will be discussed in subsequent sections.…”

Biodegradable flexible conductive film based on sliver nanowires and PLA electrospun fibers

“…Degradable flexible electronics have broad application prospects in nextgeneration wearable devices and implantable bioelectronics. [11][12][13] Wearable flexible electronics often use conductive nanomaterials to provide electrical properties. [14][15][16] Commonly used conductive nanomaterials include carbon nanotubes, 17,18 graphene, 19,20 conductive polymers, [21][22][23][24] and metal nanowires.…”

“…The prepared microelectrode has good biocompatibility, can monitor extracellular Ca 2+ dynamics in rat brain, and can be completely degraded within 15 weeks. Degradable flexible electronics have broad application prospects in next‐generation wearable devices and implantable bioelectronics 11–13 …”
