Abstract
Described herein is an apparatus for characterizing an analyte in breath and related method. The apparatus comprises an interactant that is configured to interact with the analyte in breath to generate a change in thermal energy relative to a base thermal energy. The apparatus further comprises a piezoelectric system that is coupled to the interactant, comprises at least one piezoelectric material having a material property, and generates a signal that comprises information useful in characterizing the analyte in breath. The signal is in response to a change in a material property of the piezoelectric material. The change in the material property is in response to the change in thermal energy. The apparatus may be used for a variety of applications such as, for example, personal health monitoring, clinical diagnostics, safety and law enforcement monitoring, and others.
