Sensors for Vital Signs Monitoring

<p>Sensor technology for monitoring vital signs is an important topic for various service applications such as entertainment and personalization platforms and Internet of Things (IoT) systems as well as traditional medical purposes such as disease indication judgments and predictions. Vital signs for monitoring include respiration and heart rates body temperature blood pressure oxygen saturation electrocardiogram blood glucose concentration brain waves etc. Gait and walking length can also be regarded as vital signs because they can indirectly indicate human activity and status. Sensing</p><p>technologies include contact sensors such as electrocardiogram (ECG) electroencephalogram (EEG) photoplethysmogram (PPG) non-contact sensors such as ballistocardiography (BCG) and invasive/non-invasive sensors for diagnoses of variations in blood characteristics or body fluids. Radar vision and infrared sensors can also be useful technologies for detecting vital signs from the movement of humans or organs. Signal processing extraction and analysis techniques are important in industrial applications along with hardware implementation techniques. Battery management and wireless power transmission technologies the design and optimization of low-power circuits and systems for continuous monitoring and data collection/transmission should also be considered with sensor technologies. In addition machine-learning-based diagnostic technology can be used for extracting meaningful information from continuous monitoring data.</p>
