text: The ion-sensitive field-effect transistor (ISFET), for example, is widely used in biomedical applications.
text: The earliest MOSFET sensors include the open-gate FET (OGFET) introduced by Johannessen in 1970, the ion-sensitive field-effect transistor (ISFET) invented by Piet Bergveld in 1970, the adsorption FET (ADFET) patented by P.F. Cox in 1974, and a hydrogen-sensitive MOSFET demonstrated by I. Lundstrom, M.S. Shivaraman, C.S. Svenson and L. Lundkvist in 1975.
text: An ion-sensitive field-effect transistor (ISFET) is a field-effect transistor used for measuring ion concentrations in solution; when the ion concentration (such as H+, see pH scale) changes, the current through the transistor will change accordingly.
text: In 1970, Bergveld invented the ion-sensitive field-effect transistor (ISFET).
