A new generation of flexible high resolution neural electronic interfaces.

One of the more exciting topics scientists are working on is on how to connect brain and nerve cells directly to electronics. This is interesting for many reasons, such as helping us to learn how the brain works, or allowing very advanced prosthetic devices such as artificial eyes and fully functional artificial limbs. To achieve a connection to nerve cells, it is necessary to bring special electrodes close to these cells. Preferably, a large array of such electrodes. These neural electrodes are the essential part needed for neural interfacing and are the subject of this research project. Over time, neural electrodes evolved from simple fine wires to advanced silicon needle arrays looking like tiny nail beds, fabricated using micromachining technology and containing over 100 electrical contacts. However, long term high resolution neural recording and stimulation, the final goal of neuroelectronic research, is far from reached especially because of rejection of the implant by the body over time. Therefore, we have come up with alternative concepts to the current state-of-the art that we would like to investigate. These enable unique applications and should also improve long term biocompatibility. The research involves investigating new electrode concepts, new micromachining technology and fabricating and testing of electrode prototypes.
