Low power design: where are we at?
summary
Panelists report concrete failures and fixes: many deployments that promised 5 years, deliver 2 years after firmware updates or bad power profiles; field tests at booths routinely expose hidden drains that engineers then fix. Tools for energy profiling and battery-sizing appear (Qoitech energy-optimization tooling), and a prototype router uses dual CPUs (5G + STM32) to trade power for flexibility. STM32 line claims 360 nA standby with RAM retention, hardware crypto and 18 nm FD‑SOI process nodes, plus energy harvesting and TinyML/accelerators as the most promising paths.
