Update #6: Week of February 10
Feb. 14, 2020—This week, we primarily worked on our pump and air bladder compression system, soft potentiometer limb volume measurements, and building a holder for our pulse oximeter. We also brainstormed how to integrate all our components together by making a control diagram and beginning to write pseudo Arduino code. Compression: This week, we interfaced servo motors...
Update #5: Week of February 3
Feb. 7, 2020—This week, we made air bladders for our first prototype of the automatic compression sleeve, attained SpO2 readings from our pulse oximeter, attempted to solder lead wires to knotted ends of our soft potentiometers, and continued to work on the evaluation board for bioimpedance measurements. Compression: With regard to compression, this past week we searched for...
