I used moss and Eeonyx StaTex Conductive Fiber to create a sensor that can be worn on the face and stroked. I’m wearing fishnet material that is keeping the sensor in place. It’s running through Max MSP and you can hear the change in sound according to how the moss is stroked or pressed. A further iteration would be to use something that operates off of bluetooth, for freedom of movement.
When measured with a multimeter, the resting current was 13.k, and with petting and pressing it, it would range from 10.5k to 16k.
I’m very interested in working with organic material and technology. I chose to work with Kombucha Scoby which is created by Kombucha liquid. After testing it in class, I realized it was conductive, so I used 2 sewing needles connected to wires that ran into the power and ground on my breadboard. The sewing needles were connected on the bottom part of the Scoby and the top. I used a 10k resistor to connect between the ground because I was getting a reading of 7-17k ohms depending on manipulation.
I connected this to Max Msp and mapped the values of the Scoby as it was being manipulated to the frequency of a sine wave.
- Cutting or growing kombucha scoby into different shapes i.e. strips for a kind of string instrument
- how to interact with it so it doesn’t become contaminated, if I’d use it for multiple performances
Jenna and I explored the 4 soft conductive materials provided: Velostat, Eeonyx Pressure Sensing Fabric, Eeonnyx Stretch Sensing Fabric & Eeonnyx StaTex Conductive Fiber. The first 2 needed to have conductive material on either side for ground and power. The last 2 only needed to be clipped or attached at either at either end. The results are below:
In general I noticed all of the soft conductive material, varies a lot probably due to recovery of soft material to original form, not so much that it was completely out of a certain range, but enough to have to re-calibrate frequently.
The prospect of using soft conductive material (bought, found or organic), as variable resistors really opened up PComp in general for me in an exciting way. It feels great to be a bit less reliant on store bought variable resistors.
