This thesis reports on a novel system forextracellular recordings of the activity of excitable
cells which relies on anorganic charge-modulated field-effect transistor (FET) called OCMFET.
Thebook shows how thanks to the intrinsic biocompatibility lightness andinexpensiveness of
the material used this new system is able to overcome severalproblems typical of of classic
electronic andbioelectronic. Itprovides a full description of the system together with a
comprehensive reportof the successful experimental trials carried out on both cardiac and
nervecells and a concise yet comprehensive overview of bioelectronic interfaces andorganic
sensors for electrophysiological applications.
