This would be great for measuring heart rate while asleep because I can stand wearing a watch in bed, and my watch is charging at night as well.

I think it's now fair to be concerned that future MAANG devices will use passive RF data mapping, triangulation, and harvesting to scan you, your environment, and others around you.

The future of individual freedoms can only be assured with open source software and hardware not beholden to the unbounded, extractive fetishes of governments and corporations.

So we can expect that comcast will soon be selling per-household sexual activity rate data to advertisers?

I wonder, if this would work with bluetooth, too. Would be nice to hack e.g. the new, cheaper version Pebble watch to measure heart-rate this way. I mean, possibly this could even be superimposed on the regular BT-connection signals. I presume open firmware would enable these sort of things.

I think soon it will be time to seriously consider eliminating use of Wifi in some private places and going back to speed and reliability of copper wires. WiFi is like basically illuminating an area in light that can pass through walls.

Instantly visualises social media companies monitoring individual heart rates and heart-rate social graphs and that becoming an input into their algorithm ... scary shit.

There are products already that do this: https://www.originwirelessai.com/

So how long until my ISP starts selling McDonald's data on how my heart rate reacts to their new commercials that my ISP got based on wifi signals?

Its a good effort but very pedestrian and a very low hanging fruit. Its just another academia paper that will be published.

I'd say this is far more interesting, does not use ML and credits the tech stacks that it leverages . https://people.csail.mit.edu/davidam/docs/WiMic_final.pdf
