Thanks for choosing this story. Please note that the graphene device in question does not "operate" at 26 GHz, but that this frequency is based on an extrapolation from data up to 10 GHz. 10 GHz is the highest frequency "achieved" by this transistor. See figure 6 in the paper.
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.
