电生理信号的长期稳定采集有助于疾病早期诊断康复和对人体的各种生理认知研究,与皮肤相接触的电极决定了所采集的电生理信号的质量水平。导电水凝胶由于其与生物组织相似的低杨氏模量,可调节的机械性能和高生物相容性的特点在生理电信号无创采集电极中得到了广泛应用研究。综述了近年来在提升导电水凝胶导电性能、机械性能、黏附性能、保湿性能和自愈性能的研究进展,介绍了导电水凝胶在心电、肌电和脑电无创生理电信号采集电极上的应用。
The long-term stable acquisition of electrophysiological signals contributes significantly to early disease diagnosis,rehabilitation,and various physiological cognition studies in humans.The quality of collected electrophysiological signals depends on the electrodes in contact with the skin.Conductive hydrogels,due to their low Young's modulus resembling biological tissues,adjustable mechanical properties,and high biocompatibility,have been widely applied in non-invasive physiological signal collection electrodes.This review summarized recent progress in enhancing the conductivity,mechanical properties,adhesion,moisturizing,and self-healing capabilities of conductive hydrogels.Additionally,it introduced their applications in non-invasive physiological signal collection electrodes for electrocardiography (ECG),electromyography (EMG),and electroencephalography (EEG) based on recent research developments.
