ams AS7038RB Vital Sign Sensor
The operation of the AS7038RB is based on photoplethysmography (PPG) and electrocardiogram (ECG).PPG is the most used HRM method which measures the pulse rate by sampling light modulated by the blood vessels, which expand and contract as blood pulses through them. ECG is the reference for any measurement of the bio potential generated by the heart. The AS7038RB is supported by algorithms converting the PPG and ECG readings into digital HRM, HRV, Continuous Blood Pressure and SpO2 values. The cuff-less Blood Pressure Measurement has been optimized to fulfill the IEEE Std 1708-2014.The detector includes the photo-sensor, analog front-end (AFE) and sequencer as well as application software. In addition to HRM/HRV, Blood Pressure and SpO2, the detector also enables skin temperature and skin resistivity measurements by providing interfaces to external sensors.The AS7038RB’s low-power design and small from factor is particularly well suited to application in fitness bands, smart watches, sports watches and smart patches, in which board space is limited and in which users look for extended, multi-day intervals between battery recharges.
