The upcoming wireless health revolution will be propelled by ubiquitous physiological monitoring. Electrocardiogram (ECG) and electroencephalogram (EEG) are two crucial health indicators that can only be improved with continuous monitoring over time. In this study, we propose a chest-attached, nonintrusive photoplethysmogram (PPG) measuring system for everyday use with the help Internet of Things (IoT), sensor amplifier circuits capable of adjusting the light intensity to suit clothing properties can be used without skin contact. Despite developments in wireless technology and electronics downsizing, the inconvenience and pain of wet adhesive electrodes limit the usage of wireless home ECG/EEG monitoring. In recent years, research has focused on developing non-contact ECGs and EEGs, which are wireless biopotential instrumentation systems that use non-contact capacitive electrodes that operate without skin contact. Results reveal that non-contact capacitive electrodes work similarly to electrodes made of Ag/AgCl with chest and headbands, which are presented in-depth, along with comprehensive technical information, circuit schematics, and manufacturing methods. ECG chest strap, EEG headband, or a motionless electrode location can all be used with the non-contact electrode. Future mobile health applications will benefit greatly from these IoT based wireless systems and wearable design, which is far more pleasant for patients to use than more traditional contact-based systems.
