ABSTRACT

This tutorial covers circuits and systems techniques for the integration and packaging of implantable biosensing and neurostimulation devices. Such Microsystems, dedicated for interconnections to intracortical neural tissues, are wirelessly powered up while bidirectional data are exchanged between them and external controllers. Global view of main devices will be described, case studies related to massively parallel recording of neural signals will be shown, and special attention will be paid to monitoring and microstimulation in the primary visual cortex through an optimized number of electrode arrays and power management of these bioelectronic devices.
