In this project, we want to fabricate microelectrodes on a miniaturized brain neural stimulator and encapsulate the implant to protect it from the wet tissue environment. As conventional methods typically involve photolithography to fabricate microelectrodes or expose the integrated electrodes, we will develop new process flows that rely on ink-jet printing to decrease the complexity and costs of current methods to encapsulate implants and integrate their electrodes. A state-of-the-art ink-jet printer (Dimatix Fujifilm DMP 2800) will be available to the student 24/7. Students involved in this project will gain experience with ink-jet printing techniques, electrode-tissue interface, materials for encapsulation, and neural interface.
