Electroencephalogram measurement structure

An electroencephalogram measurement structure, comprising:

• an ear-hanging structure, including a body, having an ear-hanging member disposed on one end of said body, having a first reference electrode and a second reference electrode, said first reference electrode and said second reference electrode disposed adjacent to each other, said first reference electrode and said second reference electrode disposed on one side of said body, said first reference electrode and said second reference electrode coupled to a first circuit board and configure to detect a reference electrophysiological signal at a reference part of a human body, said first circuit board coupled to an electrical jack, and said first circuit board disposed inside said body, said ear-hanging member configured for hanging on an ear of said human body;
• and
• a second circuit board, coupled to an electrical plug and a measurement electrode, respectively, said measurement electrode configured to sense an electrophysiological signal, and said electrical plug coupled to said electrical jack and configured to transmit said electrophysiological signal from said measurement electrode to said first circuit board through said electrical jack.
