It seems to me one potential benefit of super capacitors would be to quickly capture power from a charging system and then free the device to be moved away while the super capacitor trickle charges the battery at whatever rate is best for the battery.
The advantage of a super capacitor over a battery is that it can charge relatively faster as compared to a battery; but the disadvantage is that the super cap discharges also pretty quickly; Also, what about the leakage? Unless these specs are improved, I can't see how the super caps could possibly replace batteries in near future...for mobile phones. Where as the super caps could be ideal for many wearable electronics application where size matters.
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.
