Patent ID: 8877538

Claim:
A method for manufacturing a pressure sensor comprising: a substrate; a source electrode and a drain electrode on the substrate with a predetermined spacing; a flexible sensor layer disposed on the source electrode and the drain electrode; a nanostructure attached on the surface of the flexible sensor layer and comprising nanosized wrinkles that transfer normal pressure to the flexible sensor layer; and a dome structure attached on the surface of the nanostructure to maximizes pressure sensing in a 3-dimensional direction, the method comprising: arranging the source electrode and the drain electrode on the substrate; disposing a flexible sensor layer on the source electrode and the drain electrode; forming nanosized wrinkles on a thin film of a polymer material to prepare a nanostructure; attaching the nanostructure having wrinkles on the surface of the flexible sensor layer; and forming a nanosized dome structure and attaching it on the nanostructure having wrinkles.
