It promises to continuously record ECG, measure heart rate, heart rate variability, oxygen saturation, BP, core body temperature and other relevant parameters.

The VITALITI system promises to continuously record ECG. It also measures the heart rate, heart rate variability, oxygen saturation, blood pressure, core body temperature, as well as parameters like respiration, movement, steps taken and calories spent. The main sensor is worn over the shoulders, with pads touching the chest doing much of the important sensing. There’s also an ear lobe sensor that is probably in charge of monitoring the heart rate and oxygen saturation.
The whole system can stay on for up to three full days, streaming the various health parameters continuously that can be retrieved at any time using a smartphone or tablet.
