Abstract Flexible strain sensors capable of acquiring tiny mechanical signals and attaching to various irregular surfaces are becoming prevalent in physiological measurement, soft robotics, human‐machine interaction. However, the advancement flexible is substantially impeded by intrinsic compromise between sensitivity range detectable signals. Inspired multilayer structure nacre nature, a carbon nanotubes (CNTs)/graphene (GR)/graphene (GR)/thermoplastic polyurethane (TPU) mat (CGGTM) prepared electrospinning high‐pressure spraying technology. By designing with mutually non‐interfering conductive networks, resulting CGGTM possesses low detection limit (0.05% strain), high (gauge factor, GF > 152537), large (up 364% fast response/recovery time (80 ms/100 ms), excellent cyclic durability 1000 cycles). Furthermore, also exhibits satisfactory triboelectric performances when assembled into nanogenerator (TENG, 3 × cm 2 ), including output (open‐circuit voltage V oc = 135.4 V, short‐circuit current I sc 1.25 µA) power density (88 mW m −2 enabling reliable supply, self‐powered sensing, pulse monitoring capability. Finally, successfully applied collection biological multi‐gesture motion recognition assisted machine learning algorithms, which holds promise for intelligent interaction gestures future.

Abstract To compensate for the growing need flexibility in pressure-sensing wearable devices, solid–liquid mixed-phase sensors have been improved to meet application needs. Compared their all-solid-state counterparts, these exhibit improvements flexibility, conductivity, and hydrophilicity. A highly flexible piezoresistive pressure sensor utilizing a porous structure made of polydimethylsiloxane (PDMS)/ carbon nanotube (CNT)/C 3 H 8 O composites is introduced this study. The was confirmed by field emission scanning electron microscopy. Response release times were demonstrated be rapid, approximately 43 ms 62 ms, respectively. Mechanical testing revealed tensile strength 0.06 MPa Young’s modulus 0.0723 MPa, while compressive recorded at 0.0876 with 0.142 MPa. Durability assessments indicated consistent performance across 6000 cycles notable conventional PDMS hybrid CNT-based sensors, new exhibited conductivity 50 40 times, Its applications include detection mouse button clicks, monitoring human pinky joint motions, recognition within arrays. discussed holds significant potential advancements human-computer interaction technology sectors.

Abstract Flexible strain sensors have undergone significant development since their inception. Currently, most are typically designed to detect in only a single direction. However, as sensor application scenarios continue expand, challenges can arise utilizing these uniaxial applications involving multiple directions. In this work, carbon nanofiber (CNF)/thermoplastic polyurethane (TPU) nanocomposite with highly aligned and porous structure is fabricated via heat‐assisted electrohydrodynamic (EHD) printing technique, where high‐voltage electric field applied achieve high‐resolution filamentation high temperature imparts the filament. The unique architecture of promotes formation microcracks under along alignment direction, leading an ultra‐high sensitivity 750. Under transverse on contrary, limited 12.8 obtained because external effectively shared by increased spacing filaments. Based exceptional multidirectional sensing properties, we demonstrate detecting complex motions such facial muscle finger joint movements. current work provides effective strategy for fabrication anisotropic nanocomposites precisely controlled multifunctional properties. Highlights Highly was produced EHD printing. High‐voltage facilitate filamentation. High utilized impart nanocomposite. Large disparity achieved orthogonal capable human motions.
