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.
