Ask HN: Cool stuff that's still completely unregulated?
I just wanted to say that I love this post.<p>There is a huge space around """fitness""" devices that are running around the FDA regulatory process.  I think there is going to be a huge health revolution by making everybody take their weight, glucose, blood pressure, sleep statistics, and heart rate statistics every day and feed them into an AI.<p>The major techincal step forward that is happening is microneedles that can draw out interstitial fluid.  The patient doesn't feel it, and you can do things like constant glucose monitoring, and constant cortisol monitoring (which is huge) completely uninvasively.  It's going to be amazing.<p>The breakthrough device is going to be a watch that can sense glucose and cortisol all the time.  A while ago there was some PG post about wanting a tricorder, well it's coming, and it's going to look like a watch.<p>Sidenote: if anybody reading this is working in any of the labs working with these microneedles, please contact me, I would love to collaborate with you.
