Playing with Fabrics: The Eeonyx Strech Sensing Textile and star pad

For this workshop I played and experimented the Eeonyx stretch sensing fabric to send messages to processing and activate certain commands. I  wanted to create switch operations when the fabric was stretched out or not.

Originally, I was going to experiment with the Eeonyx StaTex Conductive Fibre and create a visualization of rain. When the conductive fabric was squeezed the rain would appear in the sketch. Holding something grey and soft like fibre reminded me of a rain cloud so I thought I’d try this idea. However I lacked materials and time so I went with the stretchy fabric route and would attempt the former later.

Here’s my workshop notes on a couple of the fabrics change of resistance I got to explore:

I used the AnalogOutSerial code from Arduino to get the values from the stretchy fabric. Whenever I stretched the fabric its resistance would change by one number. I wanted to translate this data to a processing sketch and change the background when the number changes.

Unfortunately this idea was much more difficult to execute then I realized. The sensor was really finicky and caused the background to flash when I stretched my sensor.

I tried this again with the touch pad sensor. The values were much more responsive when I touched it but I got the same finicky problem in Processing.

I also notice the change of resistance value would never be the same number when I closed the processing sketch.  Sometimes it would go below or jump to a high number so my if statements would not work and I would have to change the numbers.

 

Wether I had used the wrong code or was not filtering the data properly to get an on/of digital affect with analog data, I wish to explore the resistance of change with fabrics further and possibly create other scenarios and prototypes.
