This study presents experimental results on the production, characterization, and applications of three-dimensionally designed piezoelectric–triboelectric hybrid nanogenerators. The hybrid nanofiber mats were manufactured using poly(vinylidene fluoride) and thermoplastic polyurethane as the piezoelectric and triboelectric counter materials, respectively, by the simultaneous electrospinning process. Surface-engineering agents such as poly(vinylpyrrolidone), reduced graphene oxide nanoplates (rGO NPs), and zinc oxide nanowires (ZnO NWs) were utilized in three-dimensional decoration stages. The nanofiber surfaces were roughened using the sacrifice method, followed by the application of electrospraying and hydrothermal growth techniques to decorate the nanofibers with rGO NPs and ZnO NWs, thereby enhancing the device. The resulting hybrid nanogenerators were subjected to periodic compression via an applied force, resulting in a 75.0% increase in voltage density and a 169.23% increase in current density compared to the neat hybrid nanogenerator, thanks to the surface roughening treatment. Furthermore, the decorations of rGO NPs and ZnO NWs on the nanofibers contributed to a 271.80% increase in voltage density and a 230.77% increase in current density, reaching values of 2.35 kV/m2 and 3.40 mA/m2, respectively. The nanogenerators were also tested in various applications, including energy storage, device powering, and textile sensors, to demonstrate their practicality.

Wearable electronics, which include wearable sensors, energy generating textiles, textile based energy storage devices, etc. is a rising trend on materials science and textile researches for last a few decades. Textile based flexible capacitors, nanogenerators, motion sensors, photovoltaic cells have been studied greatly and these devices getting commercial for last a few years. Strain is the concept that expresses mechanical deformation rate for a material. Strain sensors are smart materials, which works according to piezoelectric and piezoresistive mechanism to determine the mechanical deformation rate of materials, that can be used in mechanical characterization, structural quality control and, more recently, wearable electronics. Piezoresistive effect defines the electrical conductivity (or resistivity) changes of a material under mechanical stress. Especially on nanocomposite based strain sensors, contact between conductive nanoparticles is interrupted and this dissociation causes the resistivity change under mechanical effect. We have used a commercial, highly flexible woven fabric as base material and its flexibility provided the stretchable character for developed sensor fabric. Combining its flexibility with conductivity of graphene and/or polyaniline, promising resistivity values were observed. Furthermore, flexible nature of graphene and brittle behavior of polyaniline clearly seen in electro-mechanical characterization. The developed fabric strain sensor can be used in smart textiles and future applications for wearable electronics.
