- Flexible electronics offer ultrathin, lightweight, and conformable form factors ideal for wearable and implantable healthcare systems.
- Current flexible microprocessors suffer from energy efficiency, circuit scalability, and computing parallelism limitations.
- A new flexible AI chip, FLEXI, has been introduced in Nature by Tian-Ling Ren and colleagues, providing cost-efficiency and robustness.
- The FLEXI chip offers significant performance improvements, including a 27.5 times increase in computational speed and less than one-third of the power consumption compared to the best existing low-temperature polycrystalline silicon flexible chips.
- Two main challenges in developing high-performance flexible chips are device variability and the lack of reliable design models.
- The team tackled these challenges by implementing a fully custom, digital-first architecture, capitalizing on the robustness of logic gates and compute-in-memory for digital operations.
