In this study, a piezoelectric harvesting device was developed using polyvinylidene fluoride (PVDF) nanofibers reinforced with either BaTiO nanoparticles or graphene powder. BaTiO nanoparticles were synthesized through the sol-gel method with an average size of approximately 32 nm. The PVDF nanofibers, along with the nanoparticle composites in an acetone-N,N-dimethylformamide mixture, were produced using a centrifugal Forcespinning™ machine, resulting in a heterogeneous arrangement of fiber meshes, with an average diameter of 1.6 μm. Experimental tests revealed that the electrical performance of the fabricated harvester reached a maximum value of 35.8 Voc, demonstrating the potential of BaTiO/ PVDF-based piezoelectric devices for designing wearable applications such as body-sensing and energy-harvesting devices.

Purpose: The purpose of this study is to develop an innovative solution for chronic wounds in high-mobility areas, such as joints, where conventional treatments are hindered by passive healing mechanisms and the need for immobilization. By designing a micro-electro-Nanofiber dressing composed of piezoelectric polyvinylidene fluoride (PVDF) integrated with antimicrobial silver nanoparticles (AgNPs), this research aims to address the dual challenges of promoting effective wound healing and maintaining joint mobility.
Methods: Herein, we developed a novel micro-electro-Nanofiber dressing using electrospinning technology, incorporating polyvinylidene fluoride (PVDF) with silver nanoparticles (AgNPs).

Bioelectronic face masks can easily collect biomarkers in saliva, in which free cortisol is abundant. However, conventional bioelectronic face masks involve significant challenges in terms of permeability and inhalation due to their nonpermeable film-type structure. Herein, we introduce a flexible and permeable nanomesh-based wearable biosensor designed for bioelectronic face masks that monitor cortisol levels.

Solid polymer batteries (SPEs) are highly desirable for energy storage because of the urgent need for higher energy density and safer lithium ion batteries (LIBs). In this work, the single-ion lithium salt PAEK-LiCPSI was synthesized by grafting 3-chloropropanesulfonyl trifluoromethanesulimide lithium (LiCPSI) onto poly(aryl ether ketone) (PAEK). Nanocellulose (NCC), PAEK-LiCPSI, and poly(vinylidene fluoride) (PVDF-HFP) were compounded to obtain NCC reinforced high-performance nanofiber composite polymer electrolytes (NCC/PAEK/PVDF) through electrospinning, which presented tensile strength of 15.

Materials and devices that harvest acoustic energy can enable autonomous powering of microdevices and wireless sensors. However, traditional acoustic energy harvesters rely on brittle piezoceramics, which have restricted their use in wearable electronic devices. To address these limitations, this study involves the fabrication of acoustic harvesters using electrospinning of the piezoelectric polymer PVDF-TrFE onto fabric-based electrodes.
