Others have demonstrated optical sensors for blood pressure and blood alcohol content. 24/7 monitoring of HR, Resp., glucose, BP, & alcohol will be interesting.

- v8xi 4y agoadd sweat ion concentration(s) to the list!
- swamp40 4y agoI'll bet you could heat up the skin to get it to sweat.
- kylehotchkiss 4y agoJust port an electron app like slack to the watch to accomplish this without dedicated hardware
- riwsky 4y agobut if you add an electron, the watch is already an ion on its own
- avalys 4y agoI worked in this field, or very close to it, for a few years. The issue is that demonstrations are relatively easy, but validation and achieving acceptable performance over the entire range of the human population and entire range of operating conditions is very hard. Yes, you can build a wearable device that mostly gets your blood pressure right, most of the time. What are you supposed to do with that? It's not a useful product (and the FDA won't let you sell it, for that reason). If you can't depend on the results, you can't quantify in exactly what way the results are erroneous, and you don't have an enormous volume of clinical data and outcome studies, etc. with your device that allows you to draw clinical conclusions about your results regardless of their errors, you have nothing actually useful.
