“…It is clear from the figure that 45 Hz is the resonance frequency for most of the samples. If the results are compared at this particular frequency, the neat polymer shows an output performance of 1.75 V (peak to peak value) which slightly enhances to 2 V for the TiO 2 containing fibers and shoots up with the presence of ZnO to 5.5 V. For the hybrid composite containing both TiO 2 and ZnO the piezoelectric peak to peak output voltage reaches 14 V, and this could be due to the maximum polarization happening at this particular composition [ 19 ].…”

Flexible piezoelectric nanogenerators (PENG) are widely applied to harvest sustainable energy from multiple energy sources. The rational and simple design of PENG have great potential in soft electronics. Here we design a highly flexible PENG using the polyvinylidene fluoride (PVDF) and its copolymer, polyvinylidene hexafluoropropylene (PVDF-HFP) with two nanoarchitectures of semiconducting metal oxides, TiO2 and ZnO. The nanotubes of TiO2 and nanoflowers of ZnO are embedded in these different polymeric media by solvent mixing, and new fiber mats are generated by coaxial electrospinning technique. This process aligns the dipoles of polymers and nanomaterials, which is normally a pre-requisite for higher piezo potential. With excellent mechanical strength and flexibility, the tailored lightweight fiber mats are capable of producing good output voltage (a maximum of 14 V) during different mechanical vibrations at various frequencies and in response to human motions. The hybrid nanocomposite PENG is durable and inexpensive and has possible applications in wearable electronics.

“…For the synthesis of stimuli-response nanocomposites, active nanofillers are mostly used because these materials can react to different stimuli. As a result, the obtained nanocomposite could respond to electric currents, light, temperature, magnetic field, pH changes, etc [30][31][32]. An example that demonstrates the effect that active nanofillers can generate when incorporated into polymer matrices is the work carried out by Chen et al, who reported the synthesis of a shapememory nanocomposite with a rapid light response and self-healing performance.…”

Nanocomposite polymers have received considerable interest in research for the last three decades. Those nanocomposite polymers that are sensitive to a stimulus such as pH, temperature, magnetism, and electricity, among others, called smart or intelligent nanocomposite polymers had received even greater attention due to their potential technological applications. Applications of these polymers include flexible electronic devices, sensors, self-healing polymers, shape-memory materials, etc. The sensitivity of the material can come from both the polymer that acts as a matrix and the nanofiller, resulting in a material that combines properties of each of its components and that each one will not have separately. This mini-review aims to provide an update on the most recent and significant applications in the area of stimuli-responsive polymer nanocomposites, emphasizing the most innovative applications in biomedicine and catalysis developed in the last three years.

“…This nanogenerator can generate 2.8 V output voltage with 2% Co‐ZnO loading only. Nanocellulose and Fe doped ZnO nanoparticle‐loaded PVDF polymer‐based hybrid nanocomposite has also been developed for the piezoelectric application by this research group (Ponnamma et al) and they reported that this hybrid nanocomposite‐based piezoelectric nanogenerator can generate 12 V output voltage which is 2.3 times higher output as compared to the pure PVDF‐HFP‐based nanogenerator. Furthermore, Fe doped ZnO incorporated PVDF‐HFP solution cast film‐based piezoelectric nanogenerator has also been reported by Ponnamma and coworkers and they have reported this nanogenerator can generate 2.4 V output voltage with 2% loading of the filler.…”

A unique potassium sodium niobate (KNN)/zinc oxide (ZnO) incorporated Poly(vinylidene fluoride) (PVDF) polymer-based hybrid piezoelectric nanogenerator has been developed by using electrospinning process.Electrospinning method has been used due to its remarkable role in improving the piezoelectric performance of the nanocomposite based nanogenerator by providing mechanical stretching and in situ poling of both the polymer as well as filler at the same time. The PVDF/KNN/ZnO electrospun nanocompositebased piezoelectric nanogenerator exhibits the maximum output voltage as compared to PVDF/KNN and PVDF/ZnO based nanogenerator. The output voltage and current for the PVDF/KNN/ZnO based nanogenerator are 25 V and 1.81 μA (when pressure is applied by the finger tapping mode) and 8.31 V and 5 μA (when pressure is applied by standard sewing machine). The synergistic effect of KNN and ZnO nanorods into PVDF polymer matrix significantly improves the resultant piezoelectric performance of the PVDF/KNN/ZnO based nanogenerator by which it has been possible to glow an LED, power density of 11.31 μW/cm 2 (finger tapping) and 10.38 μW/cm 2 (pressure applied by sewing machine). Finally, the practical applicability of the produced nanogenerator has been checked by attaching it on elbow and wrist of a human hand, which shows 90 mV (for elbow), 400 mV (front side of wrist), and 225 mV (back side of wrist) output voltage by bending and moving of the same.
