Highly Stretchable Piezoresistive Graphene–Nanocellulose Nanopaper for Strain Sensors

Abstract
Highly stretchable graphene–nanocellulose composite nanopaper is fabricated for strain‐sensor applications. Three‐dimensional macroporous nanopaper from crumpled graphene and nanocellulose is embedded in elastomer matrix to achieve stretchability up to 100%. The stretchable graphene nanopaper is demonstrated for efficient human‐motion detection applications.
