To capture the electric potentials from the organism, I have to create a split petri dish with a small bridge between each slot to allow the electricity form the organism to flow, moreover, this approach will capture the electricity only from the organism, not the medium. | To capture the electric potentials from the organism, I have to create a split petri dish with a small bridge between each slot to allow the electricity form the organism to flow, moreover, this approach will capture the electricity only from the organism, not the medium. | ||

For capturing the electricity, I use the capacitive sensor method. | |||

At the beginning, I captured the electricity form my hands for observing a number to make a differentiation between the electric potentials from human being and microorganism. | |||

Then, I connected the wires to the organism. | |||

The captured number from my hands is around 6000 - 7500, from the Physarum Polycephalum is around 10 - 21 and more stable. | |||
