Introduction
Monitoring multiple physiological parameters using biosensors is highly valuable for tracking personal wellness, the healthcare of patients, and the physiology of athletes during exercise. However, the primary challenge in terms of technical development remains keeping the technology's price affordable while ensuring effective monitoring of two or more physiological parameters (temperature, blood pressure, etc.) (1) and biomolecules (glucose, lactate, cortisol, etc.) (2).
Methods
In this regard, biosensor channel multiplexing presents an ideal solution allowing us to switch between detection channels to simultaneously measure and monitor multiple physiological parameters and biomolecules. This technology is particularly suitable for potentiometric biosensors where no current is applied after each switch, thereby minimizing noise and capacitive behavior associated with amperometric techniques.
Results
As shown, biosensor channel multiplexing provides fast response time, versatility, and non-destructive measurement. It consumes little energy, making it ideal for battery-powered application. It can be easily integrated and connected to smart devices (smartphones, tables, etc.), enabling the simultaneous detection of multiple parameters or biomolecules.
Conclusions
Multiplexing techniques are important in biosensing for better health tracker monitoring. At Electrochemistry Consulting and Services, we are committed to supporting our clients at every step of the way, starting from strategic consulting services and feasibility studies, through to the troubleshooting and diagnostics of technical issues. We also assist in the design, development, and testing of electrochemical systems and devices.
