Experimental measurements of potentials generated by the electrodes of a cochlear implant in a phantom

Abstract

The design and development of an experimental setup to measure in-vitro electric potential distribution delivered by a multichannel cochlear implant varying conditions and parameter of usage is described, with particular attention to the spatial distribution of the electric potential generated by this implant. This study enables a better comprehension of the relationships between parameters of stimulations and the electric potential delivered by the cochlear implant, fundamental to develop a more efficient and spatially localized stimulation of the nervous tissues.
