Blood pressure monitoring
So not really biohacking, but could potentially be modified in that direction. After fainting 2 or 3 times today from my extreme low blood pressure, I started looking for a wearable blood pressure monitor. I already wear a pedometer, so the addition of a blood pressure monitor does not seem like much of a stretch. However, I cannot find any completed devices, regardless of fairly complete research going back the past 5 years.
Here are the links for the articles I have been reviewing on the idea.
How possible would it be to DUI something like this? The technology is well available, and the research is all public access. Something like this would help people like me keep track of what is causing my extreme drops in blood pressure, and could easily be used in the opposite direction as well. There is already an android app developed to track BP, so that could easily be adapted into a more regular tracked system.
