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.
