Semiconductor ion sensor

0303201-186

[DEFINITION]
A sensor integrating an ion sensitive electrode with an amplifier.

[DESCRIPTION]
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.
