This paper aims to study the stability of the sodium ion sensor. The study focuses on effect of interference ions on sodium ion. The sodium ion is an indispensable element of human body for regulating physiology. Because some organ's functions or pathology affect directly by sodium ion of human blood, hence it is the most crucial to detect sodium ion of blood. That is why we study the stability analysis for the sodium ion sensor. In the stability analysis, it includes the response time, reproducibility, temperature effect, hysteresis effect, working lifetime and interference effect. We employed the extended gate field effect transistor (EGFET) to fabricate the sodium ion sensor. Moreover we used the entrapment method to prepare the sodium ion membrane, and that the polyurethane incorporates the sodium ion ionophores (B12C4) to form on the window of EGFET. The present results indicate that the good sensitivity, linear regression, rapid response time, the temperature effect, low hysteresis voltage, long working lifetime and interference selectivity coefficients. And the working range of the sodium ion concentration is between 1 M and 10−5 M. The useful working pH range of the sodium ion sensor is pH6–pH8. The experimental results exhibited the stability of RuO2/Si is better than RuO2/polyethylene terephthalate (PET).
