High temperature makes problems with silicon devices by fast electrons movement and power dissipation. Low temperature makes no problem for silicon design itself, but for mechanical design like wiring inside package, crystal oscillators or electrical interconnects. I do not feel this mechanical problems are big deals for any other IC manufacturers.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
