Villa-Arango, S., Torres Villa, R., Kyriacou, P. A. & Lucklum, R. (2016). Cavity Resonance Sensor with Disposable Analyte Container for Point of Care Testing. IEEE Sensors Journal, 16(17), pp. 6727-6732. doi: 10.1109/jsen.2016.2584240


The use of phononic crystals and resonant structures as sensing platforms paves the way to the development of new biomedical technologies. An acoustic sensor with a resonant cavity and a disposable element was investigated in this paper. The sensor consists of seven layers with high acoustic impedance mismatch. The disposable element used was a glass spectrophotometry cuvette and, during the experimentation, it was filled with different liquid analytes showing characteristic transmission features that could be used as measures to differentiate and identify them. Experimental transmission curves were obtained using an electronic characterization system that uses a double sideband modulation technique to acquire valuable information about the structure being analyzed. Simulations using the 1-D transmission line method were performed to support the experimental realizations. The frequency of maximum transmission has been found to be strongly dependent on the speed of sound of the analyte under test.
