▎ 摘  要

NOVELTY - The method involves connecting an electric stack device with a heat source. A first modulating electrode is connected with a second modulating electrode. First control signal and second control signal modulation process are performed, where the first control signal and the second control signal are periodic rectangular pulse control signal. Second control signal regulating process is performed. Graphene layer coefficient noise eliminating process is performed. A first voltage leading value of temperature information is obtained. USE - Graphene thermopile device signal reading method. ADVANTAGE - The method enables regulating seebeck factor of a graphene layer to output direct current or low frequency signal by a graphene thermopile so as to change direct current or low frequency signal into high frequency alternating current signal, so that chopping wave portion of a thermopile amplifier is cancelled. The method enables eliminating voice switch induce chopping wave and reducing soil graphene thermopile sensor system noise. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene thermopile device signal reading system. DESCRIPTION OF DRAWING(S) - The drawing shows a side perspective view of a graphene thermopile device.
