Therefore, this work proposes a self-adaptive capacitive-resistive mode-conversion pressure sensor, whose mode-converting function can be achieved by a high relative permittivity (high-κ) nanocomposite layer and a temperature sensitive insulation layer. The capacitive pressure sensing mode is constructed at the ambient temperatures below the phase transition temperature of the insulation layer, exhibiting high stability and repeatability. When the ambient temperature rises to the phase transition point, conductive pathways are formed, thus the flexible pressure sensor converts to resistive pressure sensing mode.

The solution embeds mechanics through laminate parameters derived from Tsai's invariants and constrains designs with a domain-specific grammar over ply orientations. The framework couples a high-fidelity predictor, which regresses load and stiffness, with a generator that directly produces requirement-compliant layups efficiently across data scales. Attention analyses reveal that LayupFormer captures long-range through-thickness interactions and internalises laminate principle, providing interpretable insights into the generation process. Experimental validation confirms that LayupFormer-designed layups achieve superior bearing performance and reduced variability compared with empirical baselines.

Herein, we propose a facile pyrolysis strategy to prepare aniline-functionalized elastomeric oligomers, which leverages the dynamic covalent polymerization between the abundant reactive di/polysulfide segments of vulcanizates and <em>m</em>-phenylenediamine (MPD). Upon regulating MPD dosage, MPD moieties are rationally inserted into the di/polysulfide segments and synchronously disintegrate the sulfur-based network architecture, thereby achieving MPD-functionalized oligomers (MFO) with adjustable MPD content. The obtained oligomers feature with multiple aniline handles and rubber-based segments, which can enable strong interfacial linkages between CB and rubber matrix in the composites. Even incorporating a small amount of the obtained oligomers (i.e. 0.21 wt% of MPD moieties), the thickness of the interfacial region and the CB dispersion can be considerably enhanced, leading to reductions of ∼21.3 % and ∼22.5 % in temperature rise and rolling resistance of the composites, respectively. Moreover, this also synergistically promotes tip deflection/branching and energy dissipation during crack propagation. Meanwhile, the reduction in temperature rise of composites further maintains the network robustness under cyclic loading. Therefore, the crack growth rate of the composites shows a remarkable decrease (∼64 %) at high tear energy, along with a substantial increase of ∼75 % in ultimate fatigue life.
