Abstract
In one implementation, a multi-vital-sign smartphone system detects multiple vital signs from sensors such as a digital infrared sensor, a photoplethysmogram (PPG) sensor and at least one micro dynamic light scattering (mDLS) sensor, and thereafter in some implementations the vital signs are transmitted to, and stored by, an electronic medical record system.
