Electrolyte-oxide-semiconductor field-effect transistor

from Wikipedia, the free encyclopedia

The electrolyte-oxide-semiconductor field-effect transistor ( EOSFET for short ) is a special field-effect transistor with an insulated gate ( IGFET ). In contrast to conventional metal-oxide-semiconductor field-effect transistors (MOSFETs), the gate electrode is not implemented with a metal layer , but with an electrolyte solution.

EOSFETs are used, for example, to detect neural activities, for example in brain-computer interfaces .
