There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract:
The objective of the proposed research is is to develop a robust wirelessly-powered implantable recording and stimulation system for a freely-moving animal subject. Several innovative system- and circuit-level techniques are proposed towards the development of a novel wireless power transfer (WPT) system and an inductively-powered wireless implantable neural-recording and stimulation system (WINeRS) for a freely-moving animal subject. The dissertation includes 1) a high-efficiency and adaptive wireless power transfer system,2) three-phase time-multiplexed scalable power Tx which has ability to wirelessly power a large number of distributed Rx with arbitrary angular and spatial misalignments across a large plane, 3) a novel wireless platform for electrophysiology experiments inside the standard homecage called EnerCage-HC, which takes advantage of multi-coil coupling and Kinect® based optical localization to offer an efficient and low-cost technology for wireless powering any electronics attached to a small animal subject and tract its behavior, and 4) a robust wireless implantable neural and peripheral recording and stimulation (WINeRS) system fully compatible with the EnerCage-HC system with measurement and in vivo experimental results.
