Abstract

Optical transcutaneous data links have rarely been researched, and mostly out of-body communication with high data rates has been investigated: up to 40Mb/s has been achieved with high power consumption and an obvious drawback was the implantation of a photoemitter as part of the system. Optical communication was used to control an epiretinal stimulator. The photoemitter sits in front of the lens, and a receiving discrete photodiode (PD) is placed in the line of sight. The PD is connected to a transimpedance amplifier (TIA), which is integrated on the stimulator ASIC.
