The integration of inflexible constituents onto pliable substrates is widely acknowledged as the most pragmatic approach for the realization of stretchable electronics. Nevertheless, the assurance of enduring connectivity between rigid electrode components and these compliant substrates poses a formidable quandary. In the scope of our investigation, we proffer a resolution by conceptualizing a PDMS substrate replete with strain isolation partitions, which can generate Young's modulus difference of approximately 30 times. These partitions efficaciously safeguard the steadfast linkage between rigid components and electrodes, even under diverse strain provocations, a stable connection can be maintained even when able to withstand strain exceeding 120 %. Using this substrate, we constructed a visual deformation sensing system based on microcrack type sensors. Compared with traditional flexible substrates (2 % strain), systems based on strain isolation substrates have better tensile stability (10 % strain). This groundbreaking innovation bestows stretchable micro-crack strain-sensing systems the resilience to contend with the potentially formidable rigors of everyday application.

一种基于应变隔离基板的高可拉伸性微裂纹触觉传感器系统


将不灵活的成分集成到柔韧的基材上被广泛认为是实现可拉伸电子产品的最实用方法。然而，确保刚性电极组件和这些兼容基板之间的持久连接构成了一个可怕的困境。在我们的研究范围内，我们通过概念化充满应变隔离分区的 PDMS 基板来提供解决方案，这可以产生大约 30 倍的杨氏模量差。这些隔板有效地保护了刚性部件和电极之间的牢固连接，即使在各种应变刺激下，即使能够承受超过 120% 的应变，也可以保持稳定的连接。利用这种基板，我们构建了一个基于微裂纹型传感器的视觉变形传感系统。与传统的柔性基材（2% 应变）相比，基于应变隔离基材的系统具有更好的拉伸稳定性（10% 应变）。这项突破性的创新赋予了可拉伸微裂纹应变传感系统应对日常应用中可能令人生畏的严酷条件的弹性。
