Dr. Arati Prabhakar has to be lauded for leading the way US government entities evolve with the times. She had a distinguished leadership tenure at NIST and was responsible for increasing its outreach with industries in my opinion.
Regarding DARPA funding GaN research in RF and power devices, here is a link that lists companies funded:
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.
