"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. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
