Abstract
The present invention provides a real-time luminescent piezoelectric detector capable of sensing the presence of biological and chemical agents. This detector includes a free-standing thin film that is driven by a frequency driver to produce light emitted from an edge of the thin film. A surface layer sensitive to the biological or chemical agent to be detected is disposed on the surface of the thin film. In the presence of the biological or chemical agent to be detected, the light emitted from the edge of the thin film structure is altered. A processor capable of determining the presence and/or concentration of the biological or chemical agent in question based on the altered emitted light receives an output representative of the emitted light and outputs the status of the presence and/or concentration of the biological or chemical agent in question.
