Implantable Electrochemical Biosensors for Retinal Prostheses

摘要

Progress has been made in the development of implantable electrochemical biosensors. However, to date a commercially-available long-term implantable biosensor is still out of reach. The foreign body response poses great challenges for long-term implantable devices. Retinal prostheses provide a platform for incorporation of biosensors for neural stimulation and biosensing in the human eye.

1. An implantable biosensor comprising:
a sensing element; an electronic circuit receiving signals from the sensing element and producing sensing data; an implantable hermetic package incasing the electronics circuit; and a coil for sending the sensing data from the biosensor outside the body; wherein the biosensor is of suitable size and geometry for implantation in and around an eye.
