It really isn’t the core need. The core need is industrial settings where you want to be able to fit and forget a sensor and have it alert you to problems or provide a stream of data for diagnostic monitoring.
Can it be used for spying? Maybe, assuming audio surveillance that’s a large power requirement though, so seems unlikely for the foreseeable.

- drjasonharrison 3y agoI find the pro/con for this solution in an industrial environment interesting: - adding yet another power/data line for a sensor is expensive, possibly requiring equipment to be shutdown, new mounting points to be drilled, etc. - trying to find an accessible current carrying wire that isn't further enclosed in a ferrous enclosure that would block RF. It reminds me of the time my boss suggested using inductive power for a camera in a dairy barn. It's a wet and difficult environment where urine, salt, water, temperature swings were common. How were we going to get the power to the inductive coil? Ah, yeah.
