Abstract

image

A new type of piezoresistive sensor with ultrahigh pressure sensitivity in the low-pressure range and minimum detectable pressure of 9 Pa is fabricated based on a fractured microstructure design in a graphene-nanosheet-wrapped polyurethane sponge (PUS), as described by Shu-Hong Yu and co-workers on Page 6692. This low-cost and facilely scalable graphene-wrapped PUS pressure sensor has potential applications in high-spatial-resolution artificial skin without a complex nanostructure design.
