Flexible Graphene-Based Passive and Active Spinal Cord Implants

The spinal cord, considered to be the most important path of the human body, when injured induces severe motor dysfunction. Therefore, patients affected by lesions on the spinal cord, are most of the time unable to walk, stand or perform motor activities that are trivial for healthy people. To provide a better quality of life for these patients,...

Towards a Microfabricated Flexible Graphene-Based Active Implant for Tissue Monitoring During Optogenetic Spinal Cord Stimulation

Our aim is to develop a smart neural interface with transparent electrodes to allow for electrical monitoring of the site of interest during optogenetic stimulation of the spinal cord. In this work, we present the microfabrication process for the wafer-level development of such a compact, active, transparent and flexible implant. The transparent...
