High resolution neural implants for chronic neurostimulation

High resolution interfacing between electronic circuits and brain tissue is a strongly emerging research field. Because the focus is often on measurements in brain tissue at high resolution, communication to the tissue is underexposed in the research field. In this research project several aspects of this are considered. First, the possible tissue damage during chronic use of neurostimulation with micro-electrodes will be investigated, as a function of the waveform used. Secondly, the design of the electrode contacts themselves will be optimized, looking at both material and design aspects. In addition, the doctoral project includes the investigation of the required external electronics for wireless data and power transfer between the electrical circuit and the external system.
