Nanopapers, papers made from wood-derived nanocellulose, have attracted much attention for their applications as environmentally-friendly flexible substrates due to their outstanding features including thermal stability, organic solvent resistance, sustainability, and biodegradability, etc. However, conventional nanopapers with smooth surfaces and densely-packed structures are poor in skin-breathability and skin-adhesion, which makes the applications in on-skin electronics remain unexplored. This research enhanced the skin-breathability and skin-adhesion of nanoaper by introducing porous nanostructures, and then applied it for on-skin electronics.
