Example slime recording in Faraday Cage
The electrical signals generated by three slime (Physarum) tubes were measured with 3 PhyLink units inside Faraday Cage and on open bench, see setup below:

 

Samples F1, F2 and F3 inside Faraday Cage:


Sample F1
recorded inside Faraday Cage:

Multiple fundamental frequencies (6 mHz, 12 mHz, etc) due to several slime tubes spanning electrodes.

Sample F2 recorded inside Faraday Cage:

Fundamental frequency of oscillation around 8 mHz

Sample F3 recorded inside Faraday Cage:

Fundamental frequency of oscillation around 6 mHz.

 

Samples F1, F2 and F3 re-tested with Phylink hardware (V18 unmodified sketch) on open bench (no Faraday Cage)

 

Sample F1 recorded on open bench

Fundamental frequency of oscillation around 6.6 mHz

Unable to determine fundamental frequency of oscillation for sample F2.

Sample F3 recorded on open bench

Fundamental frequency of oscillation around 7.1 mHz
