Graphene Tribotronics for Electronic Skin and Touch Screen Applications
Abstract
Graphene tribotronics is introduced for touch-sensing applications such as electronic skins and touch screens. The devices are based on a coplanar coupling of triboelectrification and current transport in graphene transistors. The touch sensors are ultrasensitive, fast, and stable. Furthermore, they are transparent and flexible, and can spatially map touch stimuli such as movement of a ball, multi-touch, etc.

A pressure-responsive triboelectric nanogenerator used to gate graphene based transistors showed a pressure sensitivity of ≈2% kPa-1 at pressure of 10 kPa.
“In a representative work, a pressureresponsive triboelectric nanogenerator was used to gate the graphene based transistors.[161] Such graphene tribotronics showed a pressure sensitivity of ≈2% kPa -1 at pressure of 10 kPa.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
