Preparation‐free and skin compliant biopotential electrodes with high recording quality enable wearables for future healthcare and the Internet of Humans. Here, super‐soft and self‐adhesive electrodes are presented for use on dry and hairy skin without skin preparation or attachment pressure. The electrodes show a skin‐contact impedance of 50 kΩ cm² at 10 Hz that is comparable to clinical standard gel electrodes and lower than existing dry electrodes. Microstructured electrodes inspired by grasshopper feet adhere repeatedly to the skin with a force of up to 0.1 N cm⁻² without further attachment even during strong movement or deformation of the skin. Skin compliance and adhesive properties of the electrodes result in reduction of noise and motion artifacts superior to other dry electrodes reaching the performance of commercial gel electrodes. The signal quality is demonstrated by recording a high‐fidelity electrocardiograms of a swimmer in water. Furthermore, an electrode with soft macropillars is used to detect alpha activity in the electroencephalograms from the back of the head through dense hair. Compared to gel electrodes, the soft biopotential electrodes are nearly imperceptible to the wearer and cause no skin irritations even after hours of application. The electrodes presented here could combine unobtrusive and long‐term biopotential recordings with clinical‐grade signal performance.

用于临床ECG和EEG记录的皮肤保形聚合物电极

具有高记录质量的免制备且符合皮肤要求的生物电势电极使可穿戴设备可用于未来的医疗保健和人类互联网。这里介绍了超柔软和自粘式电极，适用于干燥多毛的皮肤，无需皮肤准备或附着压力。电极在10 Hz时的皮肤接触阻抗为50kΩcm ²，与临床标准凝胶电极相当，但低于现有的干电极。受蚱feet脚启发的微结构电极以最大0.1 N cm ^-2的力反复粘附在皮肤上即使在皮肤剧烈运动或变形时也无需进一步固定。电极的皮肤柔顺性和粘合性能可降低噪音和运动伪影，优于其他干式电极，可达到商用凝胶电极的性能。记录游泳者在水中的高保真心电图可以证明信号质量。此外，带有柔软大柱的电极用于检测从头后部到密发的脑电图中的α活性。与凝胶电极相比，柔软的生物电势电极几乎不被穿戴者察觉，甚至在使用数小时后也不会引起皮肤刺激。此处介绍的电极可以将无干扰的长期生物电势记录与临床级信号性能结合起来。
