AS7038RB-COLM

AS7038RB-COLM is a biosensor solution with embedded ECG channel. It 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. PPG is also used to measure the blood oxygen saturation (SpO2). ECG is the reference for any measurement of the bio potential generated by the heart. Embedded ECG analog front end satisfies IEC 60601-2-47 requirements. The solution includes LED drivers, photo-sensor, analog front-end (AFE) and sequencer as well as application software. In addition, the device also enables skin temperature and skin resistivity measurements by providing interfaces to external sensors. Application includes optical sensor platform, disposable oximeter, smart patch, earbuds, fitness band, smart watch, oximeter, ECG monitoring.
