Wireless Energy and Data Transfer for Neural Recording and Stimulation Applications

This study presents design and implementation of a wireless energy and transfer system. The system is targeted to work in accordance with neural recording and stimulation purposes, more specifically for in-vivo epilepsy monitoring. A brief overview of the system is given and supported with detailed explanations of functional blocks. An in-vitro experimental setup has been designed and used for performance characterization while mimicking tissue absorption. 35% power transfer efficiency has been achieved to transfer 10 mW to the implant unit from 10 mm. Moreover, 50 kbit/s and 500 kbit/s downlink data communication has been realized with 19% and 33% power transfer efficiencies, respectively.
