Abstract :
Chronically implantable neural information transducers that interface extracellularly with nearby neurons are currently being developed for applications in rehabilitation. These devices must be both bioresistant and biocompatible. In addition to materials biocompatibility, mechanical issues are also highly important for long term applications. Connective tissue eventually invests all physical objects implanted in living tissue. Interconnects between devices or between devices and connectors that have become invested with connective tissue translate relative motion of tissues to the interconnects and devices, damaging the fragile neural structures and the implant itself. Exchanging data and power using micro-telemetry may be a solution to this persistent problem. This presentation provides an overview of significant problems with neuroprosthetic micro-devices and possible solutions to the mechanical issues using optical micro-telemetry of data and power
