AS7058 Integrated Analog Front Ends

ams OSRAM AS7058 Integrated Analog Front Ends (AFEs) are multi-vital sign monitoring devices that provide a complete photoplethysmogram (PPG), electrocardiogram (ECG), body impedance (BioZ), and electrodermal activity (EDA). PPG measures the pulse rate or blood oxygen by sampling light modulated by the blood vessels that expand and contract as blood pulses. The ECG is the reference for any measurement of the biopotential generated by the heart. With EDA, it is possible to measure the skin’s water content, and with BioZ, body composition with an electrical system.
