▎ 摘　　要

NOVELTY - The flexible graphene pressure sensor has a porous graphene body provided with several sections of piezoelectric unit connected in series. The laser printing device identifies the substrate film fixed on the bottom plate through the visual identification unit, and automatically obtains the electrode printing area. The second electrode and the piezoelectric unit are integrally formed on the substrate film to obtain the first semifinished product. The first semifinished product is coated with the protective layer to obtain the second semifinished product. The piezoelectric unit comprises multiple bending structures. The display unit displays the stress area of piezoelectric unit in the display image. USE - Flexible graphene pressure sensor based on laser printing. ADVANTAGE - The flexible graphene pressure sensor improves the detection precision, which has high precision, stable structure and convenient use. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of flexible graphene pressure sensor based on laser printing. (Drawing includes non-English language text).
