Neural interface devices that will allow signals from the human nervous system to control external equipment are extremely important for the next generation of prosthetic systems. A novel multichannel regeneration‐type nerve electrode designed to record from and stimulate peripheral nerves has been developed to allow the control of artificial hands and to generate artificial sensations. In this study a novel flexible regeneration microelectrode based on the nerve regeneration principle was designed and fabricated using MEMS technologies. The electrode, which was fabricated on a 25‐µm‐thick parylene C substrate, has multiple fluidic channels. Each fluidic channel was 100µm wide×30µm high×1500µm long and featured multiple electrodes inside them as recording and stimulating sites. They also served as guidance channels for the regenerating axons. © 2009 Wiley Periodicals, Inc.
