ABSTRACT

This paper covers an overview of multichannel massively parallel biosensing device dedicated for neural recording from the cortex. Attention is paid to describe the design techniques and assembly methods of high reliability Microsystems. These devices are optimized, first from the circuit level, to meet ultra low-power budget and all needed flexibility for efficient neurorecording. Second, at the system level, integration of multichips and their interconnections on top of electrode arrays represent challenging tasks to optimize the building of implantable intracortical sensors. Such device includes electrode arrays, preamplification front-end, data conversion, signal processing for the detection of neural events (spikes). It includes also multiple wireless links, the first one is for affording the energy to power up the whole implant, while data are exchanged bidirectionaly with a base station through two other links for data down and up links. Experimental results are shown.
