AS7026GG
General Description
1 General Description
The operation of the AS7026GG 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 AS7026GG is supported by algorithms converting the PPG and ECG readings into digital HRM,
HRV and continuous blood pressure values. The cuff-less blood pressure measurement has been
optimized to full the IEEE Std 1708-2014.
The module includes the LEDs, photo-sensor, analog front-end (AFE) and sequencer as well as
application software. In addition to HRM/HRV and blood pressure, the module also enables skin
temperature and skin resistivity measurements by providing interfaces to external sensors.
The AS7026GG’s low-power design and small form 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.
