Organic Pulse Imagery is an installation art that unites the audience with parts of the different organisms. In this project, I will capture the electrical conductivity of the organisms for conveying the massage that there are many microorganisms everywhere around us. Then, I will send that input to Max/msp to generate a 3D/2D graphic of their electrical conductivity and project that graphic onto the wall, therefore the audiences can be participated.
This idea is more likely to be an exhibition approach, which people can choose the organisms by themselves and interact with it.
The installation includes a counter which has a projector built-in, on top of the counter is a petri dishes slots that allow the participants to choose the organisms that they're interested to interact with and place it in the isolated slot which is connected to the Arduino, moreover the slots are used as an incubator for the organisms to keep them living with the suitable temperature.
This project is related to my Max/msp project here. Link to my Max/msp Project
Capturing the Electric Potentials
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.
The selected organism is Physarum Polycephalum. It was cultivated on the aforementioned split petri dish. After many attempts, I found out that the most important issue is the timing, the slime mold needs around two days to cross the bridge, after than that it will remain on its side, in contrast, earlier than that it does't cross the bridge.
The Experiment
The Setting
Here is the sketch of my ideal setting.
The electrical conductivity data from the chosen organisms is going to be generated with Max/msp into a visual, then that visual will be projected onto the wall.
The image that is projected in this sketch is from Max/msp.
