There is an incorrect comment on the Design News story.
".... So that when half the energy in one's 12 volt power pack is used up the terminal voltage is six volts. So to utilize most of the stored energy one must be able to extract power down to zero volts."
Not true, the enery is CV^2/2, so the majority of the energy is extracted in the initial voltage drop. For example, a 100F capacitor charged to 2.5V will drop to 1.77V after half the energy is extracted.
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.
