I could see it with some sort of CVD, but the problem would be keeping a crystal structure in the build. Unless you're hysically pushing atoms around, there's no guarantee to keep a planer, monocrystaline surface, and that's required for the semiconductor to work.
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.
