Piezoelectric nanogenerators (PENGs) are booming for energy collection and wearable energy supply as one of the next generations of green energy-harvesting devices. Balancing the output, safety, degradation, and cost is the key to solving the bottleneck of PENG application. In this regard, yttrium (Y)-doped zinc oxide (ZnO) (Y-ZnO) was synthesized and embedded into polylactide (PLLA) for developing degradable piezoelectric composite films with an enhanced energy-harvesting performance. The synthesized Y-ZnO exhibits high piezoelectric properties benefiting from the stronger polarity of the Y−O bond and regulation of oxygen vacancy concentration, which improve the output performance of the composite film with Y-ZnO and PLLA (Y-Z-PLLA). The obtained open-circuit voltage (V oc ), short-circuit current (I sc ), and instantaneous power density of the optimized Y-Z-PLLA PENG reach 17.52 V, 2.45 μA, and 1.76 μW/cm 2 , respectively. The proposed PENG also shows good degradability. In addition, practical applications of the proposed PENG were demonstrated by converting biomechanical energy, such as walking, running, and jumping, into electricity.

“…However, above 10 phr, the V p-p tended to deviate from proportionality under the same pressure. This deviation may be attributed to the increased concentration of BTNPs, leading to agglomeration in the nanoweb and subsequently enhancing the stiffness of the composite web [11]. This, in turn, results in reduced piezoelectric deformation under the same pressure.…”

“…Recent studies have demonstrated that the incorporation of nanorods or particles, such as ZnO [7], InN [8], and GaN [9], into PVDF or PVDF/TrFE can improve their piezoelectric characteristics. There has been a considerable rise in the number of studies focusing on piezoelectric PLA materials, and integrating nanorods or particles has also garnered significant interest [10][11][12]. BaTiO 3 nanoparticles (BTNPs) are ferroelectric material with a Polymers 2024, 16, 347 2 of 9 high piezoelectric strain constant (d 33 = 300-400 pC/N), and enhanced remnant polarization is exhibited after electrospinning a binary composite of PLA and BTNPs.…”

There has been extensive research on electrospun ferroelectric nanoparticle-doped poly L-lactic acid (PLA) nanofiber web piezoelectric devices. In this study, BaTiO3 nanoparticles (BTNPs) were incorporated into the PLA to enhance the piezoelectric properties. The composite nanofiber webs were characterized using field emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, and X-ray diffraction. The piezoelectric behavior was analyzed by measuring the peak-to-peak output voltage (Vp-p) of the samples. The sensors fabricated from the PLA/BTNP nanofiber webs exhibited higher Vp-p values than the conventional electrospun PLA sensors. Furthermore, the corona-poled PLA/BTNP nanofiber web sensors exhibited even higher Vp-p values than the non-corona-poled sensors. Lastly, the effect of stacking nanofiber webs in terms of enhancing the sensor performance was also evaluated.

“…A more eco-friendly approach to E-skin manufacturing appears to be desirable (Xu et al, 2023). The idea of reusing or degrading E-skin is becoming a reality (Zhao et al, 2023). Some E-skins that exhibit superior biocompatibility and non-polluting properties such as hydrogel E-skin have become candidates for the next-generation of biodegradable E-skin.…”

Background: E-skin (electronic skin) is an active research area in human-computer interaction and artificial intelligence.Methods: A bibliometric analysis was performed to evaluate publications in the E-skin field between 2000 and 2021 based on the Web of Science (WoS) databases.Results: A total of 4,954 documents were identified. A detailed overview of E-skin research was presented from aspects of productive countries/regions, institutions, journals, citations, highly cited papers, keywords, and emerging topics. With the emergence of new functional materials, structural design, 3D printing, and nanofabrication techniques, E-skin research has achieved dramatic progress after 2013. Scholars and institutions in China, the United States and South Korea are leading the way in E-skin research. Pressure sensor, strain sensor, and flexible electronics are the most focused directions at present and Internet of things is the most emerging topic.Conclusion: E-skin research has achieved dramatic progress but there is still quite a challenging task in practical applications. Manufacturing process simplification, cost reduction, functional integration, energy supply, and biocompatibility are vital for the future development of E-skin.
