N2 - 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 system design 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 design metric in addition to existing power, performance, and area metrics. Then, we present a novel optimization approach to place rigid components onto a flexible substrate while minimizing the loss in flexibility. We show that the optimal placement leads to as much as 5.7 × enhancement in flexibility compared to a naïve placement. We confirm the accuracy of our models 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.
