While we could probably improve current manufacturing techniques, i personally set my eyes on one of the crazy options promising orders of magnitude improvment: Quantum computing, Optical computing(like optalysys does) , Analog brain like computing, etc.
The first problem is that Moore's law is not a law, but only an observation. We have reduced the cost of integrated circuits over the years and we will continue to do that with many inovations. But there is no guarantee that it will continue forever and we all knew that.
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.
