Technology for Monitoring Heart and Brain Activity

Guides: Prof. Najib Ghatte and Dr. Payal ShahSardar Patel Institute of Technology (SPIT), Mumbai, India — Department of Electronics and Telecommunication Engineering.This paper reviews technologies for monitoring cardiac and neural electrical activity using electrocardiography (ECG) and electroencephalography (EEG). It discusses wearable sensors, analog front ends, analog-to-digital conversion, digital signal processing, artifact rejection, heart-rate variability, EEG spectral analysis, machine learning, edge computing, wireless communication, privacy, and validation. It presents a unified ECG–EEG monitoring architecture and discusses the engineering challenges involved in practical wearable health monitoring.
