About 25 years ago Nippon Mining & Sumitomo Metals ( both Japanese ) got into semiconductors. Sumitomo is one of the largest suppliers of raw Si wafers to Fabs. They even have a factory in the US.
The Chinese are merely copying with assistance from US veterans ( as reported here like this Mr. Sparks, ex Delco ) made homeless by Wall St.
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.
