摘要

电子纹身能够从人体获取难以察觉的生物电信号,被广泛应用于医疗保健和人机界面领域。纹身基底作为电子纹身的基础,需要具有仿真皮肤的机械性能、粘合性和透气性,但实现起来仍有很大难度。本研究模仿人体皮肤,在超薄薄膜(≈2 微米)的基础上设计了一种透气、粘合、机械仿肤的超级纹身基底。超级纹身与皮肤相似,具有应变适应性僵化特性,具有较高的撕裂能(5.4 kJ-m-2)和韧性(1.3 MJ-m-3)。与皮肤相比,超级纹身具有更高的粘附性、离子导电性和渗透性。可在其上加工各种导电电极,显示出其通用性,可成为稳定、低接触阻抗的理想电子纹身平台。基于超级纹身的电极可以不可见地、准确地监测交界处的吞咽弱肌电图(EMG),为吞咽困难的康复训练提供有效指导。

Breathable, Adhesive, and Biomimetic Skin-Like Super Tattoo

Breathable, Adhesive, and Biomimetic Skin-Like Super Tattoo

Electronic tattoo, capable of imperceivably acquiring bio-electrical signals from the body, is broadly applied in healthcare and human-machine interface. Tattoo substrate, the foundation of electronic tattoo, is expected to be mechanically mimetic to skin, adhesive, and breathable, and yet remains highly challenging to achieve. Herein, the study mimics human skin and design a breathable, adhesive, and mechanically skin-like super tattoo substrate based on an ultra-thin film (≈2 µm). Similar to skin, super tattoo demonstrates strain-adaptive stiffening properties with high tear energy (5.4 kJ·m−2) and toughness (1.3 MJ·m−3). Superior to skin, it exhibits high adhesion, ionic conductivity, and permeability. A variety of conductive electrodes can be processed on it, showing the universality toward an ideal platform for electronic tattoo with stable and low contact impedance. Super tattoo-based electrodes can imperceivably and accurately monitor weak electromyography (EMG) of swallowing on the junction, providing effective guidance for rehabilitation training of dysphagia.
