Week 8 (October 28, 2019 till November 1, 2019)

As a way of comparison, I conducted some experiments to measure limit of detection using the technique that I've used previoiusly: apply an AC modulation field to the sensor and acquire the spectrum of the output, while decreasing the modulation amplitude until the modulation peak can no longer be detected. With a bit of help, I made this an automated test and varied the length of FFT acquisition time (points) to check how this might affect the results. We did see that it made a difference, and this led to some interesting discussions between me, Phillip, my advisor back at NEU, and Professor Quandt.
