Textile-based electrochemical sensors
an exploration on building wearable electrochemical sensors using textile-based materials.
These explorations were able to produce some actual working sensors, but none with the fine-grained resolution necessary to detect small molecules (such as glucose or alcohol) at the concentrations present in skin-based fluids. the electrodes created using gold plated yarns produced the highest fidelity signal and largest ESA out of all fabrication methods attempted, as shown by this cyclic voltammogram: Inspired by a research paper on fractal designs for stretchable electronics, I wrote a piece of software (which was aptly named CurveTool) to help me generate space-filling, serpentine patterns in a vector-based format I could further process in Adobe Illustrator.
