dc.descriptionDATA AVAILABILITY STATEMENT : Raw data for L*a*b* and concentration are included in this article. For the pH and temperature, only summarized data (mean ± standard deviation) are reported. Additional raw data are available from the corresponding author upon reasonable request. NOTE : Presented at the Micro Manufacturing Convergence Conference, Stellenbosch, South Africa, 7–9 July 2024.
dc.description.abstractA multimodal sensor was developed to record dissolved oxygen, L*a*b* colour, temperature, and pH. This work builds on an existing model that correlates blood oxygen saturation with L*a*b* colour values. An L*a*b* colour sensor was constructed from an RGB sensor and validated against a commercial colourimeter. Sensor performance was confirmed using reference colours. Dissolved oxygen was measured with a screen-printed electrode and an analogue-to-digital converter. The results highlight potential for future optical determination of oxygen saturation, combined with electrochemical measurement of oxygen partial pressure, and compensation for pH and temperature.
