Could also see the value of this for caregiving. I caretake for my grandmother, and even something as simple as keeping airtags on her keys has been a challenge. It would be impossible for her to consistently wear some wearable health device / life alert / etc. passive health monitoring that’s not intrusive would be amazing.

Not an expert, but I suspect for many there are warning signs that someone may die in their sleep (or exercising, or ???) long before the heart finally quits. This seems like a great way to monitor for that.

when I'm old and going to die, "in my sleep" would be top of the list of ways I would want to go, (during sex is likely not going to be an option)

May we all be so lucky but "old" is relative in this case. An acquaintance did just that... in his 50's :/

If it’s during sex, would you want your sex partner to also die at the same time? Seems like it would be a troubling experience for the other person.

I’m an EMT, so not the deepest level of knowledge, but certain progressive things that will kill you (such as sepsis) would show noticeable trending in basic vitals like heart rate and respiratory rate. And sepsis is also common in geriatrics (catheter / surgery / G tube -> infection -> sepsis)

I've not followed any evolutions in this area, but there's a cool paper from 2014 about using WiFi channel state information to detect 87%(!) of falls in an experimental condition[1]. It's been a while since I read the paper, and I no longer have access, so caveats aplenty, but it's one of those things that pops into my head sometimes and I wonder if it's seen any real-world deployment.

Seems like it would be really useful in a hospital setting as well. Instead of having to wear the heart rate monitors, etc. during recovery or a stress test it could be wireless.

There's plenty of wristbands and rings with health tracking.
