The production of SymbiosisS involves both handicraft and specialized digital fabrication. For the construction we combine rather traditional textiles with soft electronics. Electronics that activate heat sensitive coating layer and flexible sensors are embedded into the soft structure. Felt is chosen as a substrate due to its exceptional material properties (sound isolation, heat preservation, biodegradability etc.). All together it is a weave of modern technology and the knowledge about textile making techniques, even crafts. In this way we give a new function to materials with static patterns or surfaces. It becomes active, as if breathing various pattern combinations in a slow, calming rhythm. The technology and materials we are using support our understanding of slow organic displays. Modularity is an important value of each member of SymbiosisO, adding a possibility to go wild with the placement.

The activation of thermochromic inks requires higher power than typical prototyping boards can provide. To address this we are developing a specialized controller platform that supports the necessary power handling. By simplifying and reducing the system form factor such electronic systems can be integrated more easily and within a wider range of static and mobile applications. Our controller continues to be developed toward an end user accessible platform under the name Heatit°C.

The newest version of SymbiosisO is powered by Heatit°C based on Arduino environment.

MATERIAL COMPOSITION
.
.
We can think of the construction elements as the different layers of symbiotic settlement. One of the layer is responsible for sensing the human action; as a response the controlling layer triggers the acting layer and indicates changes in the pattern.

layer of sensors
The pressure sensors are embedded to the base material and are part of the electronic circuit.
The first SymbiosisW used capacitive sensors for sensing the touch, for the second iteration we embedded piezo transducers to pick up the noise of friction.
When a person sits on SymbiosisS, a simple on-off soft switch is triggered.

controlling layer
We use resistive thread and nichrome wire to heat up the desired pattern. Each of the wires are controlled separately; a microcontroller is responsible for switching on/off the transistors. Heatit°C includes the transistors and manages the sensors inputs.
SymbiosisS was designed to be sit and walk on it, therefore we placed the controller outside of the material. Flat ribbon cables delivered the power along the material.
