Bi-directional telemetry This refers to the capacity of a system to send information regarding power and data in the forward direction, and information regarding the status of the implant back out. This is achieved using radio frequency (RF) transmission, and can be performed usi

Biphasic Electrical pulses in which a square-shaped pulse of one polarity is immediately followed by a similar pulse with the opposite polarity.

Bipolar stimulation "A mode of electrical stimulation whereby a differential (i.e. balanced) signal is delivered to a closely-spaced pair of electrodes.
Advantages:
- A more discrete area of neurons are stimulated, increasing channel selectivity and focus
- Focused stimulation limits channel interaction, permitting use of faster rate simultaneous processing strategies, which mimic more closely the function of the normal ear

Disadvantages:
- Fewer neurons stimulated per channel, therefore more current is required to achieve T and M levels.
- Battery drain significantly higher with bipolar stimulation"""
