Abstract
The present invention includes a method and apparatus for detecting exposure to environmental tobacco smoke by analyzing a sample of breath using electronic sensor technology, including surface acoustic-wave gas sensor technology. The method determines the presence and concentration of substance(s) (or a class of substances) indicative of environmental smoke exposure. Diagnostic software is used to identify substances where a stored library of signatures is compared to the signature obtained from the system. Signal processing and neural networks are preferably utilized in the analysis.
