Abstract

In this paper we present a prototype which is a first attempt to get continuous fetal health monitoring during labor. This system is capable of simultaneously measuring pH, SpO2 and provides a clear photoplethysmogram in real time. A Titanium nitride pH sensing electrode of 600 μm diameter in size performed a linear Nernstian sensitivity of 62.8 mV/pH within the pH range of interest from 6 to 8 and a precision of 0.14 in pH. The reflectance SpO2 sensor employed two LEDs at 630 nm and 940 nm wavelengths and is monitored by a MSP432 microcontroller; the result recorded shows close behavior to a commercial device. This work is under optimization process for a better accuracy and aiming for integration into a specific miniaturized device with a touch screen as user interface.
