Patent abstract
A detection device and method for detecting the presence of an agent in a fluid. The device includes a membrane having first and second sides. The membrane allows a stimulus, e.g. ultraviolet light, to dissolve in response to presence of the agent. A source is positioned on a first side of the membrane. The source sources the stimulus toward the membrane. A detection structure is disposed on the second side of the membrane for detecting the stimulus. The detection structure generates an output voltage in response to the intensity of the stimulus detected. As the membrane dissolves, the intensity of the stimulus detected changes.
