Well, you would certainly get a longer battery life with the phone sized form factor. I would assume that you aren't going to have it in scope mode all the time though so the watch should last much longer. Then again, I don't want to have to charge my watch a couple times a week.
It is a cool design. I went through the webpage and it might appeal every EE. But does it make a business case?...I don't think so. Why would I need a scope/waveform generator in a watch? Again, talking about the power it takes, "When using the oscilloscope, the battery will last about 12 hours"...does it make sense for it to be in a form of an watch? Why not a pocket oscilloscope in the size of a phone or perhaps using the phone, with better specs & a bit bigger display, with more buttons/nobs? Would it be so difficult to carry if it comes in the size of a mobile phone?
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.
