The power densities possible with Li-air are impressive, to say the least, but the issue of dealing effectively with variable air humidity has been a continuing issue for them. In the past I've seen musings about how MEMS-based valves might help, but this idea of using viruses to provide nano-scale structuring of the active components is an intriguing new twist. I hope it works out as well as the MIT press release indicates.
(And alas, I can't resist: I even hope the idea goes viral...)
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.
