Moreover, even after complete damage, the sensor can recover up to 95 % of its original sensitivity due to its inherent self-healing capability. Additionally, by employing fringe electric field effects and mutual capacitance responses, the 3DMFS enables dynamic proximity sensing and differentiation among seven distinct materials with a maximum detection distance reaching up to 11 cm.

Initial carbon xerogels were prepared by pyrolysis in an inert atmosphere of organic xerogels synthesized via a resorcinol-formaldehyde polycondensation route. Carbon nanofibers were grown inside the xerogel matrix by means of catalytic chemical vapor deposition of ethylene on dispersed nickel particles. Two approaches, such as an incipient wetness impregnation and a one-pot synthesis, were used for doping carbon xerogels with nickel. The kinetics of the carbon accumulation were studied in a reactor equipped with McBain balances. The activation energy values estimated for two regions with different carbon accumulation rates were found to be 80 and 100 kJ/mol. In the second region, the higher activation barrier is explained by the deactivation of nickel particles due to their partial blockage by amorphous carbon deposits. The porous structure of initial carbon xerogels was found to affect both the carbon accumulation rate and the carbon yield. Thus, the carbon yield values of 47.1–58.5 g/g<sub>Ni</sub> at 450–470 °C were obtained in the case of macroporous xerogel. The content of CNFs in the composites influences their textural characteristics. The optimal CNF loadings were found to be 25 wt% for CX-meso and 45 wt% for CX-macro. In these cases, the carbon deposition procedure should last 3 and 7 min, respectively.

In this work, a new layup concept based on layer dispersion was introduced to improve the carbon fiber volume fraction of hybrid composites while maintaining pseudo-ductile behavior. Different hybrid configurations with dispersed layups were tested experimentally and validated numerically. The results have shown that by splitting the centralized carbon layers into different dispersion units, the damage mechanisms of the hybrids can be significantly differed. Firstly, the interaction between two dispersed carbon layers was reduced with the increasing of the distance between them, which promoted more carbon layer fractures and was therefore beneficial for pseudo-ductility. Secondly, the hybrid composites tended to fail in a premature way, when the thickness of a single dispersion unit was increased to 80 μm. Compared to traditional pseudo-ductile hybrid composites, the maximum carbon layer volume fraction of pseudo-ductile hybrids with dispersed layups was up to 25.0 %, which was a 76 % improvement.
