High-frequency signal receiving and light-emitting golden mobile phone sticker

Abstract

The application provides a golden mobile phone sticker for high-frequency signal receiving and light emitting, which comprises a transparent protective layer, a printing layer, a chip layer, a gold foil layer, a hot melt adhesive layer and a release film layer which are stacked in sequence. The chip layer is integrated with a high-frequency signal receiving antenna, a rectifier filter circuit, an energy storage unit and a light emitting element. The antenna receives the high-frequency electromagnetic wave signal radiated by the mobile phone during communication, and converts the signal into direct current through rectification and filtering. The direct current is stored by the energy storage unit and is used to power the light emitting element. The light transmits through the printing layer and is emitted. The gold foil layer serves as a decorative layer. The hot melt adhesive layer bonds the layers into a whole under the condition of heating. The application directly converts the received high-frequency signal of the mobile phone into electric energy to drive light emitting, without the need of built-in battery or external power supply, so that passive light emitting is realized. The structure is light and thin, and has the functions of decoration and incoming call reminding. The preparation process is reliable, and the application is suitable for the field of high-end mobile phone decoration.
