The coil acts as a transformer coupling that transfers energy and data
information to the implant. It is connected to the processing unit by
the coil cable. The coil cable is a separate cable, which can be detached
from both the coil and the processing unit. It is connected to both
the coil and the processing unit by custom 4-pin connectors. The
connection forms a seal to prevent moisture ingress.
