Journey from Mobile Platforms to Self-Powered Wearable Systems using Flexible Hybrid Electronics

Thursday September 27, 2018
Location: CIC 4th floor Pather Hollow Conference Room
Time: 12:00PM-1:00PM


We experience a major shift in the form factor of electronic systems every 10 to 15 years. The most recent examples are the mobile platforms powered by heterogeneous system-on-chips (SoCs), while the next one is yet to dominate the market. Despite their impressive performance, mobile platforms still suffer from tight thermal constraints and resulting power consumption limitations. Furthermore, the complexity of current designs surpasses our ability to optimally control the power management knobs, such as the number, type and frequencies of active cores. The first part of this talk will overview a few recent results on the modeling, analysis and optimization of power-temperature dynamics of multiprocessor SoCs. The accuracy and effectiveness of these approaches will be demonstrated on commercial ARM and x86 (Atom) SoCs. In the second part, we will overview “Systems-on-Polymer” as a candidate technology to drive the next wave of computing. This approach has recently been introduced to combine the advantages of flexible and traditional silicon technologies. Within this context, we will present a flexibility-aware design methodology, and a self-powered flexible prototype capable of sensing, processing and wireless communication.
