The article is just marketing. RF energy harvesting has been around for more than a decade.
- tzs 3y agoThe ones I've read about before harvested from radio such as WiFi or broadcast TV. With this one they are talking about harvesting from EM noise from things that aren't intentional transmitters. Is that new?
- goodpoint 3y agoIt's not new. RF is RF.
- colinsane 3y agooverhead power lines aren’t intentional transmitters but some form of “could i power a device from the RF leakage?” gets asked on EE stack exchange at least once a year since its inception. it’s hard to point at anything in the press release and confidently say “that’s new”. i think what’s happening is that IoT/sensing is a big enough market that companies can finally invest in engineering and commercializing some of the things that have been researched over the last several decades. which imo is great to see.
- af3d 3y agoThe novelty seems to be the form-factor. It's energy harvesting made simpler for low-power applications. (A small microprocessor for example, LED's, sensors, etc.)
- buescher 3y agoThe form factor does not include the antenna.
- itishappy 3y agoCome now, we've been at this for quite a bit longer than a decade! https://patents.google.com/patent/US685955 https://patents.google.com/patent/US685955

- goodpoint 3y agoThat has little to do with modern energy harvesting.
