From: Smart wearable body sensors for patient self-assessment and monitoring

Clinical applications Location Type of Sensor Marker
Cardiopulmonary & Vascular Monitoring Wrist Ultrasound [29] Blood pressure
Multi-variable (AMON) [33] Blood pressure, blood oxygen saturation, body temp., heart rhythm
Photoplethysmographic and electrocardiograph [34, 35] Blood pressure and heart rhythm
Finger (ring sensor) Optical (heart rate) Heart rate and temperature
Radio-frequency identification (pulse & temp.) [12]
Arm or thigh Microwave reflectometric cardiopulmonary [40] Heart rate variability as a method to evaluate stress
Can be used with various equipment units Optical absorption sensor Blood oxygen, heart rate and rhythm, fatigue levels and exercise stress
ECG electrodes [36]
Phone adapter Single-channel ECG [37] Heart rate and rhythms
Seat belt of a car Wire-type strain gauge [41] Heart rate and respiration rate
Glucose Home Monitoring Arm Multi-variable [45] Blood glucose
