Abstract
A wearable breathing sensor, such as a piezoelectric chest belt system, generates a breathing signal that is analyzed by a classifier to identify apnea patterns indicating that the subject has swallowed during breathing. These breathing signals are computer-analyzed to extract inferences regarding the subject's eating and drinking patterns and thereby provide useful data for monitoring food or beverage intake for remote health monitoring.
