The present invention relates to a force or pressure sensing module using graphene, a multi-touch force or pressure sensing transparent touch screen using graphene, and a force measuring method using the touch screen. More specifically, the force or pressure sensing module, the first conductive layer is coupled to the lower surface of the flexible upper substrate; A second conductive layer coupled to the upper surface of the lower substrate; And a graphene graphene part provided between the first conductive layer and the second conductive layer and having a graphene layer composed of at least one graphene film and a tunneling barrier layer provided between the graphene layers. It relates to a force or pressure sensing module using a pin. |
