As a last resort, perhaps the device can float to the surface and recharge using solar cells on the body. Considering the cost, serious consideration must be given as to how to avoid collisions with motorized vessels. I hope a solid program is also in place to ensure it doesn't attract unwanted attention from underwater predators - especially since it generates electrical fields.
I once caught a marlin in Mexico. When I read this story, I couldn't help but think of the possibility of someone snagging this thing--what a catch, and even a better fish story.
Yes, I know it will be used much deeper than would be accessible--but still the imagination wanders....
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.
