Semiconductor ion sensor 0303201-186
A sensor integrating an ion sensitive electrode with an amplifier.
A semiconductor ion sensor is a generic term for sensors combining
an ion sensitive electrode, whose membrane voltage changes according to fluctuations of pH or carbon
dioxide partial pressure in the blood, with a semiconductor circuit to amplify that output. A field
effect transistor (FET) is often used in the semiconductor circuit section. An ion sensitive field
effect transistor (ISFET) is a typical example.
