How Common Noise and Error Sources Affect Optical Biosensing

By: Ian Chen

Abstract: Optical sensors represent the most common type of biosensor. This application note examines common noise and error sources that impact optical sensing, including the effects of confounders from the environment captured in the measurement and the physiological variations among the user population. This document also summarizes the current capabilities of wearable biosensors and discusses the future of optical biosensing applications.
