A toolset of input-output materials facilitating interactions with organic, fluid-based systems. Utilizing compounds from food, these material primitives are able to output a spectrum of colors, different degrees of shape deformation, and switch from odorous to non-odorous based upon pH value. The primitives are edible, degradable and can be combined together to create a single material with multiple output properties. This work offers new design paradigms that enable people to see, touch, smell and even taste the information around them within environmental, cosmetic, and food applications.
In the natural world, molecules are the common language used to communicate, signal and regulate behavior. These chemical codes are complex dialects, mediating interactions between systems from the environment to our bodies and food. As humans, we understand information mediated by our senses - through textures, symbols, odors, and tastes. To open up possibilities for human interaction with organic systems, Organic Primitives was developed. It is a toolset of input-output materials that facilitates the design of interactive objects. These material sensor-actuators convert pH signals into human readable outputs - changing color, odor and form in response to chemical stimuli. Organic primitives were synthesized by utilizing a selection of food-grade organic compounds as dopants for the functionalization of various biopolymers.
