AI Technical Summary

Problems solved by technology

[0003] The transparent graphene heating membrane prepared by the existing technology only has the effect of heating, and has not realized the functionalization and functional application of the membrane except for heating, thus limiting the practical use of graphene heating membranes in many aspects, such as: Transparent graphene heating diaphragms often require an external temperature detector in heating applications to monitor the diaphragm temperature in real time. In actual use, it is often necessary to paste and connect temperature sensors and other objects, which not only affects the appearance and use experience of the diaphragm group, but also In some specific use environments, the requirements for functional system applications cannot be met; in the medical field, when the human body undergoes far-infrared radiation therapy with graphene transparent heating film, it needs to simultaneously perform current output therapy, measure changes in human body resistance, and generate heat. Body temperature monitoring, external heating pressure change monitoring, etc., when using the existing heating diaphragm for heating treatment, the above functions basically cannot be realized at the same time
