摘要

A novel acoustic real-time detection of sub-wavelength biofilm in simulated waterpipes is presented in this study. The novelty of this technique is that it requires noneed for secondary methods to validate the receiver data and requires sensors withlower frequency compared to 20 MHz ultrasound sensor. The significance of thistechnology is that biofilms are of concern in many industries, such as healthcare,water, food, and others, leading to loss of profits, high downtime, and health concerns.Therefore, the quicker biofilm can be monitored, the greater the chances toavoid these issues. In this study, voltage and phase shifts of a pair of sensors positionedon each side of plastic chambers simulating water pipes were evaluated whenrandom materials were positioned in between the sensors indicating their abilityto detect materials with thickness greater than 40 μm, suggesting that the sensorarrangement can be used to detect biofilm of thickness greater than 40 μm ina closed piping system. Further, experiments performed with biofilm simulated byPolyHEMA and actual Escherichia coli (E. coli) bacteria biofilm indicated that asthe thickness of the testing medium changes, the phase shift and the voltage levelschange in response, indicating the ability of the sensors to detect not only the presenceof biofilm, but also its growth. Real-time monitoring of the system providesinstantaneous results thus enabling the user to take quick actions on controlling theformation of biofilm.
