Abstract
Abstract A multifunctional composite composed of a spacer fabric and a porous graphene‐based aerogel is proposed for sensing and impact protection applications. The combination of the mechanical properties of the spacer fabric and the electrical properties of the graphene‐based aerogel provides a versatile composite material with a strain sensitivity of 1.48, a temperature sensitivity of −0.004 °C −1 , and a protection factor of 45%. The material is also lightweight, hydrophobic, and thermally insulating. It is therefore suitable for both high‐temperature (nearly 180 °C) and low‐temperature applications. Consequently, the developed multifunctional composite has potential for use as a building material and as a smart cushion for healthcare.
