Fig. 4: Application of NB-textile in biomechanical feedback.

a The schematic diagram illustrates the weaving process of NB-textile, demonstrating the interlacing technique of alternating NB-fiber and cotton thread as the warp and weft, respectively. b A photomicrograph showcases NB-textile woven with a plain weave structure using a commercial loom(top), while a photo of NB-textile under tensile deformation exhibits minimal visible deformation(bottom). c Testing washing performance, the inset presents a digital photograph of NB-textile washing using a commercial liquid detergent in a washing machine. d A modified isolation circuit architecture was presented for passive sensing array readout. e Dynamic path recognition involves the formation of a unit where the sensing warp and weft intersect. Upon applying pressure, the curvature of NB-fiber changes (i). The path process (ii), and the corresponding electrical signal (iii). f Pressure distribution during acupressure in humans is demonstrated. g The capability of NB-textile to monitor muscle strength is showcased. h The strength of muscle groups during different gestures is analyzed.
