与皮肤电连接以监测个人健康状况是皮肤接触电生理学的基础。在临床实践中，与柔软的身体组织相比，使用刚性和笨重的预凝胶或干燥电极对用户舒适度和移动性造成严重限制，同时限制了临床应用。在这里，在这项工作中，干燥，不可感知的临时纹身电极。定制的单或多电极阵列很容易通过将导电聚合物喷墨印刷到商业贴花转印纸上来制造，这允许容易地转印到用户的皮肤上。由于它们的超薄厚度（<1 µm），可提供与皮肤的保形粘附。纹身电极-皮肤接触阻抗在短期（1小时）和长期（48小时）上进行表征，并与标准预凝胶和干电极进行比较。通过在四肢和面部的不同位置上的表面肌电图和心电图记录来验证电生理学的可行性。证明了纹身作为可穿孔皮肤接触电极的新概念，毛发可以通过该电极生长，从而可以设想在毛发密度高的区域进行非常长期的记录。所提出的材料和图案化策略使该技术适合于低成本传感设备的大规模生产。
Electrically interfacing the skin for monitoring personal health condition is the basis of skin‐contact electrophysiology. In the clinical practice the use of stiff and bulky pregelled or dry electrodes, in contrast to the soft body tissues, imposes severe restrictions to user comfort and mobility while limiting clinical applications. Here, in this work dry, unperceivable temporary tattoo electrodes are presented. Customized single or multielectrode arrays are readily fabricated by inkjet printing of conducting polymer onto commercial decal transfer paper, which allows for easy transfer on the user's skin. Conformal adhesion to the skin is provided thanks to their ultralow thickness (<1 µm). Tattoo electrode–skin contact impedance is characterized on short‐ (1 h) and long‐term (48 h) and compared with standard pregelled and dry electrodes. The viability in electrophysiology is validated by surface electromyography and electrocardiography recordings on various locations on limbs and face. A novel concept of tattoo as perforable skin‐contact electrode, through which hairs can grow, is demonstrated, thus permitting to envision very long‐term recordings on areas with high hair density. The proposed materials and patterning strategy make this technology amenable for large‐scale production of low‐cost sensing devices.
