Trying again, without cannula

• At the time, I figured there were 2 ways to measure breathing, and the other was to measure expansion of the chest/belly with some kind of belt

• Stretch sensor first returned this rubber band: http://www.adafruit.com/products/519 http://www.adafruit.com/blog/2011/11/02/new-product-conductive-rubber-cord-stretch-sensor-extras/

• It was a bit awkward to make a band I could wear around my waist at night to measure breathing.

• As expected, results showed when I was changing positions in the middle of the night, and that could be corrected for.

• But the results didn't really work out, it was hard to get enough stretch on it that could be measured easily.

• In other words, one could not tell breathing from those readings.

• Also, the band had a tendency to break if stretched too much.
