Abstract

A non-contact flexible controller comprises an electrode array, a dielectric layer and a conducting layer. The electrode array at least comprises first electrode layers and second electrode layers, each of the first electrode layers and the second electrode layers is composed of a plurality of equidistant and mutually parallel electrodes, and the first electrode layers and the second electrode layers are perpendicular to one other. The dielectric layer is an array composed of a plurality of dielectric layer modules, and the dielectric layer modules are arranged at cross positions of the first electrode layers and the second electrode layers and made of transparent materials. The conducting layer is formed on the bottom surface of a flexible substrate, and comprises a reduced graphene oxide film layer which is an array composed of a plurality of reduced graphene oxide modules, and the reduced graphene oxide modules are arranged in spaces formed by the first electrode layers and the second electrode layers and electrically connected with the first electrode layers and the second electrode layers. Besides, the invention further provides a preparation method of the non-contact flexible controller. The non-contact flexible controller is high in sensitivity.
