It seemed promising to do some experiments with sewing a BP sleeve into a shirt, then setting up an Arduino to trigger it to inflate&#x2F;deflate.  It should be possible to record the result digitally.  It&#x27;d be slightly uncomfortable, but even if it&#x27;s only once per hour, it&#x27;s still better than zero per hour.  The noise would be annoying, but I have some ideas for how to make it quiet.  But would anyone actually want such a thing?<p>Thanks for batting around the idea with me, and for the valuable references.  I didn&#x27;t know there was any other way to measure BP than the old-fashioned way.
