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.

Micro powder injection moulding
Powder injection molding (PIM) has emerged as a viable method for producing complex shaped parts at a competitive cost. The PIM process, which consists of feedstock preparation, injection molding, debinding and sintering, uses a combination of powder ...
A novel thick photoresist for microsystem technology
A thick photoresist and its processing was developed, based on acrylic chemistry, for thicknesses up to 700 µm and used for the electroforming of micro parts. This novel negative tone resist has the advantages of aqueous processing, good mechanical ...
Multi-layered and conducting polymer-based biosensing membranes
The multi-layer membrane designs of enzyme-based electrode have been proven to be a successful approach for biosensing of formate, with substantial improvement in sensitivity and selectivity. The biological interferents can be eliminated by multi-layer ...
