Electrical and Computer Engineering
Engineering Engineering is the science and
art of applying scientific andmathematical principles,experience, judgment, andcommon sense to design things
that benefit society. If people have built it, grown it,moved it, or launched it intospace, you can be sure that
engineering had something todo with it.

ARRAY FOR A COCHLEAR PROSTHESISPassive version of the active 32-site probe (optimized for guinea pig) In-vivo testing confirms earlier auditory thresholds of 20-50A and
150-300A for monopolar and bipolar stimulation, respectively. Neural response data indicates a strong dependence on
perimodiolar placement of the array. Back voltages are consistent with operation from 3V supplies
delivering 1mA and 40nC.
