“…Stretchable electronics holds great promise for various emerging applications, including flexible displays [Chen and Liu, 2013;Kwon et al, 2017;, solar cells [Hou et al, 2019;He et al, 2021;Wang et al, 2021], conformable sensors [Zheng and Cheng, 2019;, implantable transient electronics [Hwang et al, 2012;Hong et al, 2019;Song et al, 2019;Jiang et al, 2020;Lu et al, 2021], eye cameras [Song et al, 2013], stretchable antennas [Zhu and Cheng, 2018;Zhu et al, 2019;Xu et al, 2021;Zhu et al, 2021a;Zhu et al, 2021b] and medical monitoring devices [Chen et al, 2019;Park et al, 2020;Rwei et al, 2020]. One recent emphasis of stretchable electronics focuses on the design and manufacturing of novel structures at different levels for achieving high stretchability in the resulting electronic devices, including unfastened fractal serpentine interconnects [Huang et al, 2019;Liu et al, 2019;Feng et al, 2020;Nie et al, 2020],…”
