Harvesting biomechanical energy is an important route for providing electricity to sustainably drive wearable electronics, which currently still use batteries and therefore need be charged or replaced/disposed frequently. Here we report approach that can continuously power electronics only by human motion, realized through a triboelectric nanogenerator (TENG) with optimized materials structural design. Fabricated elastomeric helix inner electrode sticking on tube the dielectric layer outer...
Triboelectric nanogenerators (TENG) are a possible power source for wearable electronics, but the conventional electrode materials TENG metals such as Cu and Al that easy to be oxidized or corroded in some harsh environments. In this paper, metal material is replaced by an electrical conducting polymer, polypyrrole (PPy), first time. Moreover, utilizing PPy with micro/nanostructured surface triboelectric layer, charge density generated significantly improved, more superior of layer. As...
A soft, stretchable, and fully enclosed self-charging power system is developed by seamlessly combining a stretchable triboelectric nanogenerator with supercapacitors, which can be subject to harvest energy from almost all kinds of large-degree deformation due its soft structure. The washable waterproof owing structure hydrophobic property exterior surface. worn on the human body effectively scavenge various motion, it demonstrated that wearable source able drive an electronic watch. This...
In this work, polypyrrole/graphene doped by p-toluenesulfonic is prepared as an active material for supercapacitors, and its capacitance performance investigated in various aqueous electrolytes including HCl, LiCl, NaCl, KCl with a concentration of 3 M, respectively. A rising trend observed according to the cationic mobility (Li(+) < Na(+) K(+) H(+)), which due effect on ionic conductivity, efficient ion/charge diffusion/exchange relaxation time. On other hand, long-term cycling stability...
Nanostructured Fe<sub>3</sub>O<sub>4</sub> is intrinsically prone to aggregation, which hinders insertion and extraction of lithium ions.
Polypyrrole is a promising candidate for supercapacitor electrode materials due to its high capacitance and low cost. However, the major bottlenecks restricting application are poor rate capability cycling stability. Herein, we control morphology of polypyrrole-graphene composites by adjusting graphene content, causing typical "cauliflower" polypyrrole gradually turn into homogeneous nano-sheet these composites. The consequently exhibit good thermal stability, protonation level (37.4%),...
Coulombic efficiency especially in the first cycle, cycling stability, and high-rate performance are crucial factors for commercial Li-ion batteries (LIBs). To improve them, this work, Al2O3-coated natural graphite powder was obtained through a low-cost facile sol-gel method. Based on comparison of various coated amounts, 0.5 mol % Al(NO3)3 (vs mole graphite) could bring about smooth Al2O3 coating layer with proper thickness, which act as preformed solid electrolyte interface (SEI) to reduce...
Triboelectric nanogenerators (TENG) are able to convert mechanical energy into electricity. In this work, a self‐powered electrochemical synthesis circle is designed, in which the electrode material of TENG, polypyrrole (PPy), prepared by pulse output PPy‐based TENG itself. The based on PPy from (SPSPPy) presents competitive performance compared those made commercial sources. A supercapacitor that fabricated SPSPPy has far superior than synthesized conventional galvanostatic method....
Abstract Developing scalable methods to produce large quantities of high‐quality and solution‐processable graphene is essential bridge the gap between laboratory study commercial applications. Here an efficient electrochemical dual‐electrode exfoliation approach developed, which combines simultaneous anodic cathodic graphite. Newly designed sandwich‐structured graphite electrodes are wrapped in a confined space with porous metal mesh serve as both electrodes, enabling sufficient ionic...
We investigated low-hydrogen SiN films prepared by a low temperature (350 degrees C) PECVD method. The impact of SiH(4)/N(2) flow ratio and radio frequency power on the hydrogen content in was studied. In this work, we demonstrated low-loss sub-micron waveguide using corresponding optimal films. propagation loss found to be as -2.1+/-0.2 dB/cm at 1550 nm with cross-section 700 x 400 nm. results suggest that grown can used photonics integrated circuits for new generation communications applications.
