Dr. Marcia Silva, an Inventor at University of Wisconsin, Milwaukee (UWM), has developed a novel technique that uses an acoustic wave system to detect the amount of biofilm inside a pipe, tank, or tube containing a fluid. The method applies to any medium which is filled with fluid and intended for human use or consumption and potentially for surfaces in addition. By utilizing this early and non-invasive detection system many issues with people getting sick from these microbial consortia can be reduced and eliminated. This technology uses a transmitter, receiver, and electronic controller to send, receive and detect an ultrasonic signal based on the attenuation (the reduction of the amplitude of a signal) and phase shift of the signal. Although attenuation by single reflection is too small to detect, the attenuation by multiple reflections is large enough to be accurately characterized.
