摘要

导电水凝胶为共形电子皮肤和自供电系统提供了重要的前景。然而，开发具有多种功能的水凝胶，包括可拉伸性、自愈性、组织粘附性和生物相容性，仍然是一个重大挑战。在本研究中，通过原位掺杂聚（3,4-乙烯二氧噻吩）：聚（苯乙烯磺酸盐）（PEDOT:PSS）在Laponite®（LAP）交联低聚乙二醇（OEG）甲基丙烯酸甲醚共聚物中制备了多个物理交联的纳米复合水凝胶。通过共价和非共价相互作用的结合，再加上金属离子掺杂，所制备的导电纳米复合水凝胶具有优异的拉伸性能（~450%）、高自愈效率（~95%）、强大的组织力（~ 0.5 N/cm2）和良好的生物相容性。这些特点使其非常适合应用于人体运动监测的皮肤适形应变传感器。此外，它还可以用作摩擦电纳米发电机中的柔性电极，实现人机交互的触觉感应，并展示其在自供电电子产品中的潜力。

Efficient multi-physical crosslinked nanocomposite hydrogel for a conformal strain and self-powered tactile sensor

Conductive hydrogels offer significant promise for conformal electronic skin and self-powered systems. However, developing hydrogels with multifunctionality, including stretchability, self-healing, tissue adhesion, and biocompatibility, remains a significant challenge. In this study, multiple physically crosslinked nanocomposite hydrogels were developed through the in situ doping of poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) in a Laponite® (LAP) crosslinked oligo ethylene glycol (OEG) methyl ether methacrylate copolymer. Through combined covalent and non-covalent interactions, coupled with metal ion doping, the developed conductive nanocomposite hydrogel achieved excellent stretchability (~450%), high self-healing efficiency (~95%), robust tissue force (∼0.5 N/cm²), and good biocompatibility. These features made it highly suitable for applications as a skin conformal strain sensor for human motion monitoring. In addition, it could be used as a flexible electrode in triboelectric nanogenerators, enabling tactile sensing for human–machine interactions and demonstrating its potential in self-powered electronics.
