Merging textiles with advanced energy harvesting technology via triboelectric effects brings novel insights into self-powered wearable textile electronics. However, fabrication of a comfortable textile-based nanogenerator (TENG) high outputs remains challenging. Herein, we propose highly flexible, tailorable, single-electrode all-textile TENG (t-TENG) both wear comfort and outputs. A dielectric modulated porous composite coating containing poly(vinylidene fluoride)-hexafluoropropylene copolymer barium titanate nanoparticles is constructed on conductive fabric to counterpart positive glass fiber through knotted yarn bonding, maintaining the superiority strong triboelectricity. Through synergistic optimization charge storage modulation dissipation offset by electrical poling, remarkable (261 V, 1.5 μA, 12.7 nC) are obtained from miniaturized, lightweight t-TENG (2 × 2 cm2, 130 mg) an instantaneous power density 654.48 mW·m–2, as well excellent robustness device durability over 20,000 cycles. The also exhibits sensitivity 3.438 V·kPa–1 in force region (1–10 N), demonstrating great potential TENG-based intelligent sports sensing applications for monitoring correcting basketball shooting hand foot arch posture. Furthermore, 110 light-emitting diode arrays can be lightened up gently tapping this miniaturized t-TENG. It offers source scheme integrating clothing utilizing skin grounded electrode, revealing its ease integration biomechanical capability. This work provides attractive paradigm next-generation electronics well-balanced performance comfort.

Triboelectric sensors have received extensive attention in wearable self-powered sensing, electronic skin, and smart medical treatment due to the characteristics of low-cost diverse material choices, but sensitivity detected range are greatly limited development scale commercialization triboelectric sensors. Herein, we propose a binary insulator/conductor electrification sensor (BICS) assembling an aminated porous gelatin aluminum (Al) as positive tribolayer MXene@polyvinylidene fluoride (MXene@PVDF) nanofiber film negative tribolayer. Because layer, Al can not only generate charges effect also capture from electron tunneling effect. And for MXene@PVDF MXene is embedded PVDF enhance generation tribo- piezocharge under contact with gelatin/Al film. Owing large number generated, BICS shows ultrahigh short current 1.06 mA, which 1000 times higher than previous related research (usually ∼μA). exhibits excellent 3.33 V kPa-1 wide detection Pa kPa, making it ideal full pressure human activity monitoring. Our findings provide novel significant strategy constructing high-performance

To efficiently collect mechanical energy from the marine environment and reliably provide clean for low-power equipment is main aim of this study. In study, a triboelectric-piezoelectric hybrid generator with flapping wing structure was designed, inspired by movement birds. Piezoelectric thin films serve as elastic supports vertical contact-separation-mode triboelectric nanogenerators (TENG) can an external output. And coupled cantilever beam piezoelectric harvester concentrated mass, achieving significant reduction in eigenfrequency entire structure. Making its close to frequency range waves more suitable collecting random environments. indoor sink, electrical output be cached capacitor enable normal operation small electronic devices. When power provided cathodic protection, open-circuit potential 304SS reduced 270 mV, greatly improving corrosion resistance. This provides design consideration future supply future.

Poly(dimethylsiloxane) (PDMS) is a predominantly utilized negative triboelectric material in nanogenerators (TENGs). Its surface topography and synergistic interaction with positive materials significantly impact the performance of TENGs. Here, we propose simple cost-effective approach to promote dual-surface-modified TENG using microwave-structured aluminum (MW-Al) together microcone-structured polydimethylsiloxane (MC-PDMS). Laser-engraved molds were employed cold-imprint MC-Al pattern MC-PDMS. Subsequently, heights microcones generated under varying laser powers on TENGs was explored. The output MW-MC-TENG increased microcone from 0 228 μm. MW-MC228-TENG, highest cone heights, can produce best open-circuit voltage 157 V short-circuit current 78.5 µA, resulting more than 37% improvement compared flat polymer. Furthermore, MW-MC228-TENG showed power density 16.4 W/m2, sufficient 198 LEDs. Finally, proposed integrated as sensor into an warning system. We triggered voice–visual when impacted, proving its potential for intelligent home safety monitoring.
