机械柔性、印刷和可拉伸的电子产品正在获得发展势头。虽然在器件和电路层面的快速发展正在进行中，但研究人员还没有设想灵活形式的系统设计。介绍了基于柔性混合电子技术（FHE）的聚合物上系统（SoP）概念，将柔性电子技术与传统硅技术的优势联合收割机结合起来。首先，我们正式定义的灵活性作为一个新的设计指标，除了现有的功率，性能和面积指标。然后，我们提出了一种新的优化方法，将刚性元件放置在柔性基板上，同时最大限度地减少柔性损失。我们表明，最佳的布局导致了高达5.7倍的灵活性增强相比，一个天真的布局。我们使用有限元法（FEM）模拟器确认了我们的模型和优化框架的准确性。最后，我们使用一个具体的硬件原型来展示SoP的概念，并讨论了SoP的架构和设计中的主要挑战。
Mechanically flexible, printed, and stretchable electronics are gaining momentum. While rapid advancement is well underway at the device and circuit levels, researchers have yet to envision the systemdesign in a flexible form. This paper introduces the concept of System-on-Polymer (SoP) based on flexible hybrid electronics (FHE) to combine the advantages of flexible electronics and traditional silicon technology. First, we formally define flexibility as a new designmetric in addition to existing power, performance, and area metrics. Then, we present a novel optimization approach to place rigid components onto a flexible substrate whileminimizing the loss in flexibility. Weshow that the optimal placement leads to asmuch as 5.7x enhancement in flexibility compared to a naive placement. We confirm the accuracy of ourmodels and optimization framework using a finite element method (FEM) simulator. Finally, we demonstrate the SoP concept using a concrete hardware prototype, and discuss the major challenges in the architecture and design of SoPs.
