AB - A proposed transcutaneous monitoring system utilizing a CO2 sensor with ion-selective electrodes for monitoring transcutaneous carbon dioxide partial pressure (TcpCO2) is detailed in this study. The system incorporates an STM32F103 processor as the control chip, designed with a modular solution. The hardware circuit design scheme include power supply circuit, PID temperature control circuit, signal conditioning circuit, digital-analog conversion. Additionally, an Microsoft Foundation Classes(MFC)-based human-computer interface is designed for data communication, display and storage. The above system was validated through experimentation, demonstrating that the designed TcpCO2 monitoring system can achieve a temperature measurement accuracy of ±0.1o C and a temperature control accuracy of ±0.2o C. Furthermore, the system was able to detect changes in partial pressure of CO2 (pCO2) within the range of 0-100 mmHg, with a detection limit(LOD) of 1.38 mmHg and a relative standard deviation(RSD) of 7.07% for pCO2. Furthermore, the electrochemical workstation system, initially small and simple, has been enhanced with the addition of a weak current detection channel and a constant potentiostat circuit, thereby enabling the system to broaden its functionality. Ultimately, this system shows promising potential for application in clinical medicine and health monitoring
