Patent ID: 8838198

Claim:
An electrode system, comprising: (a) a plurality of electrode modules, wherein each of the plurality of electrode modules comprises an electrode housing, wherein each electrode housing defines a substantially central opening, wherein the portion of the electrode housing that defines the substantially central opening forms an annular inclined surface; (b) a plurality of flexible connectors coupled with the plurality of electrode modules, wherein the flexible connectors comprise flexible circuitry configured to communicate signals from the electrode modules, wherein the flexible circuitry comprises traces formed on a flexible substrate; and (c) a plurality of sensors, wherein each sensor of the plurality of sensors is configured to removably couple with a corresponding one of the plurality of electrode modules, wherein the plurality of electrode modules are configured to sense evoked response potentials from a test subject, wherein each sensor is further configured to communicate sensed evoked response potentials to the associated electrode module; wherein each of the plurality of flexible connectors has a bent shape extending upwards from the electrode modules.
