In-plane micro-supercapacitors (MSCs) possess higher volumetric energy density and are thus more compact compared with traditional aluminum electrolytic capacitors (AECs). As a result, developing in-plane MSCs with AC line filtering function is desired to replace the AECs and integrate with other electronic devices. Here, highly stretchable integrated system for in-plane MSCs with AC line filtering and UV detector were fabricated by designing buckled micro-electrodes based on SWCNT film and TiO₂ NPs. Although gel electrolyte was used in these MSCs, they still show an ultrafast frequency response with a phase angle of -75.2° because of their unique structure. Such MSCs thus can function as the AC line filtering devices. Furthermore, their AC line filtering behavior remains almost unchanged even stretched up to 200%. Further coating TiO₂ NPs on the buckled SWCNT micro-electrodes is able to endow the MSCs with another ability of UV photodetection with the sensitivity of 6.2. Importantly, such integrated device can still show stable photocurrent response and capacitance behaviors at different stretching times and even repeated stretching 100 times. The rational design of such stretchable integrated system for MSCs with AC line filtering and UV photodetector will pave the way for the applications in assembling supercapacitors and other electronics into highly stretchable integrated devices.

面内微型超级电容器（MSC）具有更高的体积能量密度，因此与传统的铝电解电容器（AEC）相比，其体积更小。结果，期望开发具有交流线路滤波功能的平面内MSC来代替AEC并与其他电子设备集成。在此，通过设计基于SWCNT薄膜和TiO _2的弯曲微电极，制造了具有AC线过滤和UV检测器的面内MSC的高度可拉伸集成系统。NP。尽管在这些MSC中使用了凝胶电解质，但由于其独特的结构，它们仍显示出超快的频率响应，其相角为-75.2°。这样的MSC因此可以用作AC线路过滤设备。此外，即使扩展到200％，它们的交流线路滤波性能也几乎保持不变。进一步涂层TiO ₂弯曲的SWCNT微电极上的NP能够使MSC具有6.2的紫外光检测能力。重要的是，这种集成器件在不同的拉伸时间甚至重复拉伸100次时仍能显示出稳定的光电流响应和电容性能。对于具有交流线路滤波和紫外线光电检测器的MSC，这种可伸缩集成系统的合理设计将为将超级电容器和其他电子设备组装到高度可伸缩集成设备中的应用铺平道路。
