Stretchable circuit technology, as the name implies, allows an electronic circuit to adapt to its surroundings by elongating when an external force is applied. Based on this, early authors proposed a straightforward metric: stretchability-the percentage length increase the circuit can survive while remaining functional. However, when comparing technologies, this metric is often unreliable as it is heavily design dependent. This paper aims to demonstrate this shortcoming and proposes a series of alternate methods to evaluate the performance of a stretchable interconnect. These methods consider circuit volume, material usage, and the reliability of the technology. This analysis is then expanded to the direct current (DC) resistance measurement performed on these stretchable interconnects. A simple dead reckoning approach is demonstrated to estimate the magnitude of these measurement errors on the final measurement.
可拉伸电路技术，顾名思义，允许电子电路在受到外力时通过伸长来适应其周围环境。基于此，早期的作者提出了一个简单的指标：可拉伸性——电路在保持功能的同时能够承受的长度增加百分比。然而，在比较不同技术时，这个指标往往不可靠，因为它很大程度上依赖于设计。本文旨在证明这一缺点，并提出一系列替代方法来评估可拉伸互连的性能。这些方法考虑了电路体积、材料使用情况以及该技术的可靠性。然后将这种分析扩展到对这些可拉伸互连进行的直流（DC）电阻测量。展示了一种简单的航位推算方法来估计最终测量中这些测量误差的大小。
