It sounds like you're assuming that RF energy harvesting is theoretical but in practice an unattainable dream. Samsung has for several years been selling a TV remote control that uses RF energy harvesting. It's real; it works outside the lab for actually-useful stuff.
In light of that, this news release has a reasonable amount of information about how their research improves on the prior state of the art. They shouldn't have to expend any effort in a release such as this to convince users that a technology that has already gone mainstream is real and useful and worth improving upon.
- iancmceachern 2y agoI've worked on many products which had hoped to incorporate it, but ultimately didn't. It does work well for applications like you highlight which require very very low power levels for very intermittent use. Things like a desk calculator or a IR remote. As soon as you need any kind of "real" power for anything other than intermittent use it becomes a problem. You can only beam so much power without cooking everything in between, usually that amount of power is less than we need.
