HIGHLIGHTS• Owing to the great robustness, continuous conductivity, and geometric construction of a steel wire electrode, the FST-TENGs demonstrate high stability, stretchability, and even tailorability.• By knitting several FST-TENGs to be a fabric or a bracelet worn on the human body, it enables to harvest human motion energy.• The FST-TENGs can also be woven on dorsum of glove to monitor the movements of gesture.ABSTRACT Continuous deforming always leads to the performance degradation of a flexible triboelectric nanogenerator due to the Young's modulus mismatch of different functional layers. In this work, we fabricated a fiber-shaped stretchable and tailorable triboelectric nanogenerator (FST-TENG) based on the geometric construction of a steel wire as electrode and ingenious selection of silicone rubber as triboelectric layer.Owing to the great robustness and continuous conductivity, the FST-TENGs demonstrate high stability, stretchability, and even tailorability. For a single device with ~ 6 cm in length and ~ 3 mm in diameter, the open-circuit voltage of ~ 59.7 V, transferred charge of ~ 23.7 nC, short-circuit current of ~ 2.67 μA and average power of ~ 2.13 μW can be obtained at 2.5 Hz. By knitting several FST-TENGs to be a fabric or a bracelet, it enables to harvest human motion energy and then to drive a wearable electronic device. Finally, it can also be woven on dorsum of glove to monitor the movements of gesture, which can recognize every single finger, different bending angle, and numbers of bent finger by analyzing voltage signals.

Precise control of structures offers a great opportunity to efficiently tune the catalytic performance of nanomaterials, enhacing both their activity and durability. Herein, we achieve a new class of Pt islands on 3 D nut-like PtAg nanocrystals by exploiting the lower electronegativity of Ag in conjunction with the galvanic replacement of catalytically active Pt to Ag. Such nanostructures coated with Pt nanoparticles, exhibiting exposed facets, and active surface composition enhance formic acid oxidation electrocatalysis with optimized PtAg nut-like catalysts and achieved a factor of 4.0 and 2.4 in mass and specific activities (1728.3 mA mg and 3.31 mA cm ) relative to those of the commercial Pt/C (431.2 mA mg and 1.41 mA cm ), respectively. Moreover, such 3 D PtAg nut-like catalysts also display great enhancement in durability with less decay for at last 500 cycles, showing a great potential to serve as promising catalysts for fuel cells and other applications. Our work provides a fundamental insight on the effect of the morphology toward liquid fuel electrooxidation, which may pave a new way for the fabrication of highly efficient electrocatalysts for fuel cells.

To keep pace with the rapid development of portable electronic devices, the demand for stable batteries with enhanced electrical capacities is also growing rapidly, but such demands are not easily met. Thus, energy-harvesting technology is an alternate solution, in which unintentionally abandoned energy is scavenged to supply electricity to portable electronics. Given that motion associated with daily human activities can involve large amounts of reusable energy, biomechanical energy harvesting has received significant research attention. [10][11][12][13][14][15][16][17][18] Several portable biomechanical energy-harvesting platforms are available based on piezoelectric, electromagnetic, and triboelectric effects. They offer the promise of generating electricity for standalone electronics without the need for external wiring.Triboelectric energy harvesting, which is based on the combination of contact electrification between two different material surfaces and electrical induction, has been spotlighted as a promising technology due to material selection diversity, high efficiency, and shape adaptability. [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] Previous studies of triboelectric energy harvesters, also known as triboelectric nanogenerators (TENGs), have found that the only requirement for generating electricity through a TENG is sequential contact and separation of two different material surfaces, making the TENG a promising portable energy-harvesting platform. [35][36][37][38][39][40][41][42][43][44][45][46] In addition, the advantageous characteristics of the TENG enable it to be used for self-powered sensing applications. [47][48][49][50] The operating principle of a TENG is based on the presence of charges on the surface of the material rather than its volume, so the volumetric power density has the potential to be improved far more than is the case with other energy-harvesting platforms. So far, the most widely and frequently used method to increase the output power is to introduce micro/nanoscale topography on the surface of the TENG to generate a large amount of electrical charges during its operation. In addition to modification of the contact surface, intentional control of the kinematics of the contact layer movement by using mechanical components can improve performance substantially. Given that almost all biomechanical energy has the rare characteristics A triboelectric nanogenerator (TENG) is a promising energy harvester that exploits the combination of contact electrification between two different material surfaces and electrical induction. In this study, a handheld-TENG (HH-TENG) is developed to harvest biomechanical energy effectively, especially energy generated from finger motions, which is one of the most common body movements involving lots of energy. To enhance the electrical output performance of the device while minimizing the inconvenience caused by carrying it, a rationally designed lightweight power transmission unit is adopted. As a result, an extremely high number...
