Advances in Scalable Implantable Stimulation Systems for Neuroprostheses using Networked ASICs

Damage or degradation to the central and peripheral nervous systems due to injury or disease results in loss of neural function in various parts of the body. Neuroprostheses may assist in partial restoration of function and mobility using neurostimulation. This tutorial describes recent advances in scalable implantable stimulation systems using networked ASICs. It discusses how they can meet the ever-growing demand for high- density neural interfacing and long-term reliability. A detailed design example of an implantable (inductively linked) scalable stimulation system for restoring lower limb functions in paraplegics after spinal cord injury is presented.
