The development of wearable and large-area energy-harvesting textiles has received intensive attention due to their promising applications in next-generation functional electronics. However, the limited power outputs conventional have largely hindered development. Here, combination with stainless steel/polyester fiber blended yarn, polydimethylsiloxane-coated nonconductive binding a high-power-output textile triboelectric nanogenerator (TENG) 3D orthogonal woven structure is developed for effective biomechanical energy harvesting active motion signal tracking. Based on advanced structural design, maximum peak density can reach 263.36 mW m-2 under tapping frequency 3 Hz, which several times more than that 2D TENGs. Besides, its collected capable lighting up warning indicator, sustainably charging commercial capacitor, powering smart watch. TENG also be used as self-powered sensor constantly monitor movement signals human body. Furthermore, dancing blanket designed simultaneously convert perceive body movement. This work provides new direction multifunctional potential electronics, home security, personalized healthcare.
