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