Abstract：
Understanding psychology is an important task in modern society which helps predict human behavior and provide feedback accordingly. Monitoring of weak psychological and emotional changes requires bioelectronic devices to be stretchable and compliant for unobtrusive and high-fidelity signal acquisition. Thin conductive polymer film is regarded as an ideal interface; however, it is very challenging to simultaneously balance mechanical robustness and opto-electrical property. Here, a 40 nm-thick film based on photolithographic double-network conductive polymer mediated by graphene layer is reported, which concurrently enables stretchability, conductivity, and conformability. Photolithographic polymer and graphene endow the film photopatternability, enhance stress dissipation capability, as well as improve opto-electrical conductivity (4458 S cm-1@>90% transparency) through molecular rearrangement by π-π interaction, electrostatic interaction, and hydrogen bonding. The film is further applied onto corrugated facial skin, the subtle electromyogram is monitored, and machine learning algorithm is performed to understand complex emotions, indicating the outstanding ability for stretchable and compliant bioelectronics.
摘要：
理解心理学是现代社会的一项重要任务，它有助于预测人类行为并提供相应的反馈。监测微弱的心理和情绪变化需要生物电子设备是可伸展的和兼容的，以进行不显眼和高保真的信号采集。导电聚合物薄膜被认为是理想的界面；然而，同时平衡机械鲁棒性和光电性能是非常具有挑战性的。这里,我们报道了一种基于石墨烯层介导的光刻双网导电聚合物的40nm厚的薄膜，同时实现可拉伸性，导电性和顺应性。光刻聚合物和石墨烯赋予薄膜光图案化能力，增强应力耗散能力，以及通过π-π分子重排提高光电电导率（4458Scm-1@>90％透明度），静电相互作用和氢键。我们进一步将薄膜涂在波纹面部皮肤上，监测细微的肌电图，并执行机器学习算法来理解复杂的情绪，表明可拉伸和柔顺的生物电子学的杰出能力。本文受版权保护。保留所有权利。
