Abstract

The invention provides a graphene electrode and a liquid material sugar content detection system and detection method using the same. The detection system comprises a sweep frequency constant flow source, a graphene electrode, a signal conditioner, and a computer. The graphene electrode is inserted into a liquid substance to be measured. The external electrode A terminal, the external electrode B terminal, the internal electrode A terminal and the internal electrode B terminal of the graphene electrode are connected to a four electrode probe method resistance measuring circuit. Two terminals are exciting terminals. A sweep frequency constant current voltage, which is sent by the sweep frequency constant flow source, from low frequency band to high frequency band is loaded on the exciting terminals. The other two terminals are measuring terminals and are arranged on the inner sides of two exciting terminals. Signals, which are output by a signal output terminal between two measuring terminals, are amplified by the signal conditioner and sent to a computer. A four electrode resistance measuring method is used to measure the sugar content of a liquid substance or judge whether a liquid substance contains sugar or not. The daily sugar intake can be calculated. The daily change of sugar intake can be analyzed and displayed automatically. People can calculate the intake of sugar from liquid substances in each day.

Description

technical field [0001] The technical field of electrochemical analysis and detection of the present invention specifically relates to a graphene electrode, a detection system and a detection method for the sugar content of a liquid substance using the graphene electrode. Background technique [0002] Carbon materials are widely used, including both the hardest diamond in the world and the softest graphite. In the past two decades, research on carbon nanomaterials has been at the forefront of technological innovation. In 2004, British scientists discovered that the sp 2 Graphene, a new type of two-dimensional atomic crystal composed of hybrid-connected monoatomic layers, is currently the most ideal two-dimensional nanomaterial. Graphene is composed of carbon atoms on a dense layer of crystal lattice, and its thickness is only 0.35nm, which is the thinnest two-dimensional material in the world. Graphene exhibits many excellent properties: high mechanical strength, up to 130...
