Sensors Converge 2021

Human vital monitoring has moved from the doctor’s clinic to people's wardrobes. With more vital monitoring wearable devices entering the market with each day, it is incumbent of the sensor system designers to come up with the right combination of the power management and sensor solution which can guarantee low power consumption and form factor without compromising on the fidelity of the sensor measurements.   Specifically when it comes to pulse oximetry, understanding the correlation between the typical power requirements of the LED transmitters and the SNR characteristics of the optical sensor module is essential to get the system design accurate.
