Why not use a lithium battery? More IoT press-release fantasy. You could post 50 of those every day. -- John Larkin Highland Technology, Inc lunatic fringe electronics

Interesting diode though, for other applications. Now we need it to become available for 10c/pop at Digikey. IoT is hyped to the hilt with all sorts of fantasies. Then there are those who ... just do it and no press releases. I have one such project on the lab bench for debug right now. Soon it'll be out there in the field without much fanfare. -- Regards, Joerg http://www.analogconsultants.com/

Will you do us a little fan faring after it's out? Curious! Mikek

I thought harvesting radio power was generally illegal. NT
On a sunny day (Fri, 27 Sep 2019 10:10:48 -0700 (PDT)) it happened

Every radio does that to some extend. Or is there a maximum power level above which it becomes illegal [where you are]?

I'll ask the client and if ok I'll do that. It's in the oil business and another (different client) in the ag business. -- Regards, Joerg http://www.analogconsultants.com/

Not if it's your own WiFi signal. Some of the old broadcast-power fantasies are creeping into reality, and RFID tags were only the first bit of the crawl.

It i much older than that. There were some self powered crystal receivers, in which there was a fixed additional resonant circuit tuned to a strong local broadcast station. The voltage was rectified and used to power some amplifier stages in the actual freely tunable weak signal section.

it's not always going to be your own if such things get widely deployed
