A multi­touch force­sensing transparent touch screen based on graphene film

摘要

The present invention relates to a power or pressure sensing module using graphene, a multi touch power or pressure sensing transparent touch screen, and a power measuring method using the touch screen and, more specifically, to a power or pressure sensing module using graphene which includes a first conductive layer joined to the underside of a flexible upper substrate; a second conductive layer joined to the top surface of a lower substrate; graphene layers which are arranged between the first and second conductive layers and composed of at least one graphene film; and a graphene unit having a tunnel ring barrier layer arranged between the graphene layers.
