Memristors and neuromorphic networks for high definition bioelectric diagnostics and therapy

Bioelectric signals within human body control vital human functions. Abnormal variation in these bioelectric signals would impact human health, e.g. leading to deadly conditions such as cardiac arrythmias. The present state of bioelectric signal monitoring relies on microsensors and actuators placed on soft substrates which helps in local data collection...
