  • Method for forming potassium/sodium ion sensing device applying extended-gate field effect transistor
    Patent number: 7164162
    Abstract: A potassium/sodium ion sensing device applying an extended-gate field effect transistor, which using an extended-gate ion sensitive field effect transistor (EGFET) as base to fabricate a potassium/sodium ion sensing device, using the extended gate of the extended-gate ion sensitive field effect transistor as a signal intercept electrode, and immobilizing the hydro-aliphatic urethane diacrylate (EB2001) intermixed with electronegative additive, potassium ionophore, sodium ionophore, and the like, to fabricate a potassium/sodium ion sensing electrode. The present invention utilizes the photocurability and good hydrophilicity of the hydro-aliphatic urethane diacrylate (EB2001), and fixes potassium/sodium ionophore, can obtain a non-wave filter, single-layer, stable signal potassium and sodium ion sensor.
