One usually expects more details in an article titled " ... details .. " ! For a start how about figures / photos showing various 3-d stacks mentioned as a proof of existence but also some dimensions / performance / yield data. Otherwise its more of the same old hype that has dogged the reporting of 3-d stack technology development.
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.
