ABSTRACT
AbstractYarn‐woven triboelectric nanogenerators (TENGs) have greatly advanced wearable sensor technology, but their limited sensitivity and stability hinder broad adoption. To address these limitations, Poly(VDF‐TrFE) and P(olyadiohexylenediamine (PA66)‐based nanofibers coaxial yarns (NCYs) combining coaxial conjugated electrospinning and online conductive adhesive coating are developed. The integration of these NCYs led to enhanced TENGs (NCY‐TENGs), notable for their flexibility, stretchability, and improved sensitivity, which is ideal for capturing body motion signals. One significant application of this technology is the fabrication of smart insoles from NCY‐TENG plain‐woven fabrics. These insoles are highly sensitive and possess antibacterial, breathable, and washable properties, making them ideal for real‐time gait monitoring in patients with diabetic foot conditions. The NCY‐TENGs and their derivatives show immense potential for a variety of wearable electronic devices, representing a considerable advancement in the field of wearable sensors.
