Week 9/10

We will calculate the resistance values from the voltage values we received using the resistance measured on the orings. We will also integrate a LED light and threshold value into arduino to simulate the alert to a dehydrated individual.

Our results met our expectations. Unfortunately  we were not able to integrate pulse oximetry.  Many modifications from our original proposal. We did not use matlab or a DAQ, but instead used arduino and LabView. The orginal circuits we designed had to be modified completely.

The red line represents tests done with moisture and salt on the fingers emulating sweat, the green line represents only salt on the fingers and the blue line is a dry test, emulating normal hydration.

In future work, I would expect to design a microcircuit, with small orings that could be applied to the skin, with internal power supply. I would try to collaborate in research with MC10 in their development of a flexible band-aid like waterproof circuit to monitor hydration levels.
