A MICROFABRICATED INTERFACE FOR NEURAL RECORDING AND STIMULATION

Neural interlaces are microfabricated systems able to record and to st imulate regenerated and intact nerves. We present herein a microdevice fabricated in the framework of the ESPRIT INTER project 8897 which se ems particularly attractive for basic research in neurophysiology and even for future clinical applications. The microsystem is a hybrid dev ice comprising a silicon die, incorporating electrodes to establish el ectrical connection with the regenerated nerve, housed in a polymer gu idance channel and connected to an implanted signal preprocessing inte grated unit. The fabrication of microsystem components, their assembly and recent in vivo results are described.
