Abstract
Progress in microelectronics and information technology fuels the drive for development of a neural interface between a nervous system and electronics. Miniaturization of neural implants represents the cutting edge of this effort. These devices will be capable of delivering dynamic and personalized therapies that will benefit a large group of patients. However, miniaturization of neural implants comes with a challenge of designing thin film insulation and electrodes that can perform reliably in the body. The electrochemistry toolbox can be used to create a robust neural interface that will last for a patient lifetime.
