Reduction in electronic components for an fNIRS system for monitoring cerebral hemodynamic activity

In certain cases, it is necessary to use several sensors that record a certain event or situation that is occurring in the control plant. Such as medical instruments whose sensors are placed in different areas of the patient's body, either recording electrical activity of the heart (electrocardiogram) or the brain (electroencephalograph). One of these cases is near-infrared spectroscopy systems (fNIRS), which require a substantially high number of sensors that record the hemodynamic activity of the cerebral cortex by means of photodiodes placed in different areas of the scalp.
