长期表皮电生理（EP）监测对于疾病诊断和人机协同至关重要。人体皮肤上覆盖着毛发，毛发平均每天生长 0.3 毫米。这阻碍了皮肤和干燥表皮电极之间的稳定接触，导致超长期 EP 监测期间出现运动伪影。因此，准确、高质量的 EP 信号检测仍然具有挑战性。为了解决这个问题，报道了一种新的解决方案——毛状皮肤自适应粘弹性干电极（VDE）。这项创新技术能够绕过毛发并填充皮肤皱纹，从而产生持久且稳定的界面阻抗。 VDE 在长达 48 天和 100 个周期的时间内保持稳定的界面阻抗。 VDE 在心电图 (ECG) 监测（甚至在剧烈胸部扩张期间）和大应变期间的肌电图 (EMG) 监测中能够非常有效地屏蔽毛发干扰。此外，VDE 可以轻松连接到颅骨上，无需任何脑电图 (EEG) 帽或绷带，使其成为脑电图监测的理想解决方案。这项工作代表了 EP 监测领域的重大突破，为以前监测多毛皮肤上的人体 EP 信号这一具有挑战性的问题提供了解决方案。
Long‐term epidermal electrophysiological (EP) monitoring is crucial for disease diagnosis and human–machine synergy. The human skin is covered with hair that grows at an average rate of 0.3 mm per day. This impedes a stable contact between the skin and dry epidermal electrodes, resulting in motion artifacts during ultralong‐term EP monitoring. Therefore, accurate and high‐quality EP signal detection remains challenging. To address this issue, a new solution—the hairy‐skin‐adaptive viscoelastic dry electrode (VDE) is reported. This innovative technology is capable of bypassing hair and filling into the skin wrinkles, leading to long‐lasting and stable interface impedance. The VDE maintains a stable interface impedance for a remarkable period of 48 days and 100 cycles. The VDE is highly effective in shielding against hair disturbances in electrocardiography (ECG) monitoring, even during intense chest expansion, and in electromyography (EMG) monitoring during large strain. Furthermore, the VDE is easily attachable to the skull without requiring any electroencephalogram (EEG) cap or bandage, making it an ideal solution for EEG monitoring. This work represents a substantial breakthrough in the field of EP monitoring, providing a solution for the previously challenging issue of monitoring human EP signals on hairy skin.
