Low-Power Bioelectronics for Massively Parallel Neuromonitoring

Currently emerging intracortical biosensing devices are promising alternative to allow studying the neural activity underlying cognitive functions and pathologies, understanding neurons interactions, locating onset seizures, detecting mind driven decisions, etc. This talk covers low-power analog circuits and packaging techniques used for the design and integration of biosensing Microsystems. Such devices are interconnected to intracortical neural tissues, and include high-reliability wireless links used to power up such implanted devices and bidirectionally exchange data with external base station. Global view of typical devices altogether with corresponding multidimensional challenges will be described. Special attention will be paid to report two case studies: 1) Automatic detection of action potentials from massively parallel channels, and 2) Epilepsy seizures monitoring and onset treatment.
