Data Acquisition For Wearables And In-Patient Monitoring

In-patient monitoring of blood pressure, heart rate, and pulse oximetry require very sensitive analog front ends (AFE's) designed from a system perspective. Analog techniques to lower power consumption of the AFE's while maintaining SNR will be discussed. Challenges for power management in wearables and digital processing needed for next generation patient monitoring will be discussed from the context of improving patient comfort, without sacrificing performance. This paper describes some of the critical parameters and design approaches for state-of-the-art monitoring systems focusing on signal acquisition and intelligent signal processing.
