@Peter Clarke: some how the numbers you cite above and the ones by iSuppli don't correlate. For instance, iSuppli is forecasting MEMS growth in consumer & mobile opportunity at ~$4.5B by 2015. If you take out mobile & tablets, there is $3B opportunity in the 'consumer' products? I wonder what are these consumer products that are poised to grow so much with MEMS in them... I know auto's use many sensors but not all of them are MEMS-technology based.
@Peter Clarke: see also my comments under your colleague's article on the same topic:
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. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
