N2 - Electrobiochemical and eletrophysiological signals indicate human physiology, health, and activity performance. It is still a big challenge to detect these biosignals due to the lack of sensing material. Here, we report a high-entropy material for electrobiochemical and eletrophysiological signals sensing. The high-entropy material consists of the conventional transition metallic elements of Fe, Co, Ni, Cu, and Zn. This high-entropy biosignal sensing material is able to detect the concentration of the biomarker of glucose and electrophysiological signals of Electromyography (EMG), Electroencephalography (EEG), Electrocardiography (ECG). The limitation of the glucose detection is 3.3 μM with the sensitivity of 2861 μA mM−1 cm−2. The HEA electrode also presents good linearship to the glucose concentration in PBS. The cell assay and skin assessment results also demonstrate the excellent biocompatibility of this HEA electrode, indicating good feasibility to the real biosamples. The contact impedance of this HEA electrode is lower than the conventional dry electrode, which leads to the good capability in electrophysiological signals detection. This report not only extends the application of high-entropy material in the field of biomedical engineering but also provides a new pathway for electrobiochemical and eletrophysiological signals detection.
