    We basically want a device that can send a frequency into the body between 1Hz - 1000Hz and measure the impedance value for each of the frequencies. Then, I would like a list of the top 10 highest impedance values and their corresponding frequencies. We would then send those 10 frequencies back into the body with a frequency generator until those impedance values drop.
