Abstract
There is an increasing demand for technologies that can monitor the pH of wounds and of skin in realtime, which indicates the progress of healing and the physiological condition of the skin. We have developed a novel wearable platform for the real-time monitoring of the pH of skin and wounds. A highly conductive flexible cotton sensor fibre was fabricated. This exhibited significant antibacterial properties and a rapid, selective Nernstian sensitivity (vs. a wearable fabricated Ag/AgCl pseudoreference electrode) over the broad pH range of 2.0 - 12.0 when analysing only a 50 μl sample of pH-adjusted artificial sweat matrices.
