Nice choice in problem to design for! I had raynauds issues a lot when I was younger. It only pops up a handful of times a year now. I know the best fix for me was to soak my hands in extremely hot water for a couple of minutes. I wonder if that can be replicated in a glove…
Also, interesting talk in regards to trying to fix the problem at the source. It’s probably not directly relate-able, but it would be cool if you could use a mechanism like a medical tubing pump (ex: http://www.buch-holm.com/en-GB/Assortment/Tubing-Pumps.aspx ) to increase bloodflow externally. Unforunately, the blood vessels near the surface of the skin are return and not send.
anyway, neat idea! I look forward to seeing how you progress with it.
