Here are some facts for you
* sleep number beds have sensors in them that detect heart rate
* they do this by detecting pressure differences in the air mattress
* these are effectively microphones, right? and quite sensitive
- emilamlom 2y agoDo they really detect heart rate through pressure sensors? That seems like it'd have so much noise the data would be unusable. Edit: Looks like they couple it with some fancy statistical analysis to get accurate enough data. Interesting
