A forming cell instrumented with a multi-camera 3D digital image correlation (DIC) system was built to enable precise reconstruction of the morphology of the formed 3D preforms and any wrinkles that occur. Quantification of wrinkles and their variability was conducted and their (lack of) correlation with the NCF material's macro-scale shear and bending behaviour was analysed. Meso-scale material and process variabilities were also measured and quantified. This was followed by a sensitivity analysis on their effect on wrinkling variability and highlighted the prime importance of tow-orientation and fabric pre-shear.

This paper addresses the inverse design of strain fields for hierarchical architectures by integrating efficient forward prediction with precise inverse optimization. Forward prediction models are developed to accurately predict the physical properties and performance metrics of these materials, while inverse optimization algorithms determine the optimal material distribution to achieve desired outcomes. We propose a machine learning approach that utilizes a recurrent neural network (RNN)-based forward prediction model trained on finite element analysis data, achieving over 99% accuracy. An evolutionary algorithm-based inverse optimization model is then used to identify the optimal material configuration to reach the desired strain fields.

The successive ionic layer adsorption and reaction (SILAR) technique is used to prepare a range of NTCS thin films, as battery like electrode, and the optimized NTCS3@NF electrode displayed exceptional results, overtaking all previously reported ternary sulfides. The NTCS3@NF electrode achieved an impressive specific capacity (Cs) of 1708 C/g at 5 A/g, with 100 % capacity retention and coulombic efficiency after 20,000 cycles. The superior performance of the introduced electrodes is attributed to the effective direct growth of thin film over an excellent conductive substrate and avoiding creating dead surface area by using polymer binders. The inherent connection between the prepared thin film and substrate decreases the overall resistance and facilitates electron transfer across the interface. Also, the thin film porosity helps in effective ion diffusion between the electrode/electrolyte interface. Moreover, the NTCS3@NF//Activated Carbon (AC)@NF hybrid supercapacitor device (HSC) delivered an outstanding energy density (ED) of 20 Wh/kg and a power density (PD) of 12,909 W/kg at 10 A/g, retaining 76 % capacity and 81.2 % coulombic efficiency even after 100,000 cycles, surpassing the performance of leading HSCs.

The high-performance SSECs was prepared through gravity induced sediments of silver nanoflakes, which not only exhibit extremely low sheet resistance of 4.8 mΩ/sq (the conductivity is 5.12 × 10<sup>6</sup> S/m) but also superior stretchability (up to 300 %). The resistance variation of SSECs upon stretching is very small, which can satisfy the application requirements as analog circuit systems. Copper pads embedded in SSECs not only solve the problem of interconnecting with commercial rigid components and integrated circuits but also solve the problem of nagging issue of vulnerable connections between rigid and soft parts. The SSECs can be integrated into a permeable medical dressing by lamination, which is fully compatible and strong adhesion to the skin. As a demonstration, a skin circuit has been fabricated as the platform to integrate a temperature sensor and rigid circuitry to establish a skin temperature sensing system.
