Abstract: ABSTRACT AN AQUEOUS ELECTROLYTE GATED ELECTROCHEMICAL TRANSISTOR DEVICE AND A METHOD OF FABRICATION THE SAME The present invention discloses a method for fabricating an aqueous electrolyte gated, planar side gated biocompatible electrochemical transistor device and the device fabricated thereby. The method comprises forming source, drain, and laterally positioned gate electrodes on a substrate, depositing a dielectric layer to define an active channel region, and depositing a p type organic semiconducting channel between the source and drain electrodes. The channel material comprises Poly(3,4 ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) integrated with a biocompatible ionic liquid to enable mixed ionic– electronic conduction. An aqueous electrolyte is introduced to establish ionic coupling between the channel and the side gate electrode, enabling electrochemical modulation of channel conductivity at low operating voltages. The planar side gated configuration eliminates the need for an external reference electrode and allows simplified electrolyte integration by drop casting. The fabricated device exhibits low voltage operation, high on/off current ratio, fast response time, and stable performance in aqueous environments. These characteristics of the invention enable high transconductance and signal amplification, resulting in an improved signal-to-noise ratio for accurate detection. The method thereby provides a robust and biocompatible platform for sensitive, stable, biocompatible detection of biochemical analytes sensing and electrophysiological signal acquisition, facilitating reliable, low-noise interfacing with biological systems for next-generation biosensing applications.
