DESCRIPTION
Motivated by the high level of flexibility exhibited by spider webs, scientists have developed a novel design for highly flexible and sensitive piezoresistive sensors based on an elastomer-filled graphene-woven fabric (E-GWF) structure. This technique mimics the distinct core-shell structure of spider webs. This fabrication method could also be extended to other 1D and 2D materials for many emerging practical applications. In addition to excellent sensing capability, the E-GWF also shows unusual switching behavior at large strains owing to the reversible cracking and reconnection of interconnected graphene tubes.
