Abstract
A method including causing current to flow from a first electrode of an intra-cochlea electrode array to a second electrode of the intra-cochlea electrode array at a plurality of temporal locations, measuring, at a third electrode and a fourth electrode of the intra-cochlea electrode array, a voltage induced by the flowing current at the plurality of temporal locations and determining that a change between the voltage measurements at the third electrode and the fourth electrode has occurred from the first temporal location to the second temporal location.
Claims20
A method comprising:
- measuring a voltage, induced by an electric field, at a plurality of intra-cochlea electrodes located in a cochlea, wherein the voltages are measured relative to a common reference electrode separate from the plurality of intra-cochlea electrodes where the measurements are taken;
- monitoring the relative magnitude of the measured voltages over time;
- and
- detecting a voltage change across the plurality of intra-cochlea electrodes based on the monitored relative magnitude that is representative of a voltage change at the reference electrode.
