My heartbeat “stops” every time I take my watch off to charge it.

My heartbeat “stops” every time I take my watch off to charge it.
- yellowapple 8y agoI don't know if any fitness trackers actually do this, but I'm sure it's possible to differentiate between "I'm not on the user's wrist" and "I'm on the user's wrist and not detecting a heartbeat". Skin (with or without a pulse) and air should have different electrical resistances, for example. Also, I'm pretty sure the case of "oh no I can't feel a heartbeat - oh wait, I'm on the charger" is detectable, too (that is: if it's charging, don't assume the user is dead because of an inability to detect a pulse).
