The “Vital Sign Detection & Healthcare”[1] section is very interesting, thank you! I am looking for a way to measure the heartbeat of a single person in a completely non-invasive manner (so without contact) and I see that it can be done with Wi-Fi (2019 Paper [2]). However, I’ve noticed that there are a lot of methods (video analysis, thermal camera, etc.), but they are hard to find as ready-made products at a reasonable price. The simplest solution is under-mattress sleep trackers, but unfortunately they are not an option for me. 1. https://github.com/Marsrocky/Awesome-WiFi-CSI-Sensing#vital-sign-detection--healthcare https://github.com/Marsrocky/Awesome-WiFi-CSI-Sensing#vital-... 2. https://arxiv.org/abs/1908.05108 https://arxiv.org/abs/1908.05108

Interesting. I'd be interested in a breathing sensor that can work on someone working at a computer.

  I’m sure it can be done with a normal camera and enough light, especially with the advancement of AI technologies in recent years. I haven’t had time to experiment, but if you have an iPhone, you can try this app [1] I installed yesterday to study its feasibility. On the homepage, there is a video [2] explaining more as well, and their paper [3]. 1. https://www.rouast.com/vitallens/ https://www.rouast.com/vitallens/ 2. https://www.youtube.com/watch?v=_0HHjovI8hc https://www.youtube.com/watch?v=_0HHjovI8hc 3. https://arxiv.org/pdf/2312.06892 https://arxiv.org/pdf/2312.06892
