"Make the cell too small, and you run the risk of degrading data stability unless you can boost Eb. Working with an asymmetric bit shape and thicker ferromagnetic layers can modestly increase Eb, but choosing a material with higher magnetization provides much greater benefit" seems to suggest must continually change materials to scale. But that's not practical scalability.
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.
