Stimulation Electrodes

To solve the challenge of long-term sustainable high resolution contact to neurons we need to find ways to combine smart interfacing technology with flexible bioelectronics. Furthermore, we need electrode materials that allow each electrode on the probe to be efficient both for recording and stimulation. In previous work we have developed microfabrication and assembly technologies that allow us to combine the flexible interfaces (polyimide microtechnology) with silicon based technology (CMOS chips). In NeuraViPeR we push this further by increasing the number of interconnections from a few tens to thousands. This includes the development of processes that allow us to scale up manufacturing, characterization and test without compromising quality and reliability of each contact.
