ams AS7058 High Performance Vital Sign - Analog Frontend
The AS7058 is an integrated multi-vital sign monitoring device, which provides 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, which expand and contract as blood pulses through them. 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, the body composition with an electrical system.
OSRAM Chip LED, SFH 2705
Silicon PIN Photodiode
OSRAM MULTILED™, SFH 7018A
The SFH 7018A & SFH 7018B feature a highly reflective QFN package for significantly increased light output. Their sophisticated 2-cavity design reduces interferences between green chip on the one hand and red and IR chip on the other hand. Furthermore, the 2 cavities enables the light sources to be optimally placed relative to their respective photodiodes. Overall this leads to higher accuracy of measurement of vital signs (e.g. heart rate, SpO2).
The SFH 7018A is optimized for low Vf at high current allowing operation without voltage booster in many cases.
