Abstract

A 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.
Keywords: blood oxygen saturation; screen printed electrodes; L*a*b*; dissolved oxygen; temperature sensor blood oxygen saturation; screen printed electrodes; L*a*b*; dissolved oxygen; temperature sensor
