Polyimide Neural Probe for Chronic Sensing of Neural Activity and Micro-Positioning

The goal of this research is to develop a mechanically flexible and biocompatible neural probe for in-vivo monitoring of unit neural impulses in the brain. In this research we present an implantable flexible polyimide-based neural probe that can minimize mechanical impact into the brain. Our device also features a micro-drive device which allows us to vertically adjust the probe after surgical implantation. This presentation will present the design and fabrication methods of a flexible polyimide probe and a microdrive.
