> the researcher designed ultralow power SR-rectenna I think they are just researching / developing / improving the efficiency of RF-to-DC power conversion. This research focused on using spin diodes. The article itself is a bit sensationalist. Perhaps translation issues. I do not know. Here's the source paper: https://www.nature.com/articles/s41928-024-01212-1 https://www.nature.com/articles/s41928-024-01212-1 Here's a slightly more readable article: https://www.electronicdesign.com/technologies/power/power-supply/energy-harvesting/article/55137416/electronic-design-advanced-spin-rectifier-overcomes-challenges-of-harvesting-low-level-rf https://www.electronicdesign.com/technologies/power/power-su...
