摘要： A passive acoustic wave sensor system for monitoring the quality of liquids, such as engine oil, is disclosed. The sensor system has an acoustic wave sensing device for generating a propagating acoustic wave and for detecting changes in frequency or other propagation characteristics of the acoustic wave caused by acousto-electric interactions between the liquid and the wave at an interactive region of the device. An antenna is integrated in the sensing device for receiving an interrogation signal and for transmitting the output response of the sensing device. The output response can be analyzed to determine the conductivity, pH or other electrical characteristics of the liquid. One or more reference devices may be utilized to compensate for mechanical effects of the liquid and temperature or other environmental effects. The sensing and reference devices can be configured as SH-SAW, SH-APM, FPM devices or other acoustic wave devices.

摘要： The invention relates to a thin film aluminium nitride ultrasound transducer, a method of manufacture the transducer and a test component upon which a thin film aluminium nitride ultrasound transducer is deposited. The aluminium nitride film may be (002) orientated with its c-axis normal to the surface of a substrate made of glass or a composite material. The invention also includes a system for non-destructive testing wherein a pulse is emitted from an ultrasound transducer to propagate through the test component and a reflected pulse is detected by the aluminium nitride thin film ultrasound transducer. The ultrasound transducer can be integrated into engine components such as bearings.

摘要： The present invention provides a liquid viscosity sensor comprising an ultrasonic source, a sampling body and an ultrasonic receiver. The sampling body includes a sampling face contactable by a sample of liquid, in use. The source is operable to generate a longitudinal ultrasonic wave which follows a path through the body to the sampling face and onwards to the receiver. The body is configured such that the longitudinal wave emanating from the source is transformed into a horizontally polarised shear wave prior to reaching the sampling face, and the horizontally polarised shear wave is re-transformed into a longitudinal wave before reaching the receiver. There is provided a sensor adapted to utilise the interaction of a horizontally polarised shear wave at a liquid solid interface to measure viscosity, while eliminating the need to provide both a source and receiver configured to generate and receive horizontally polarised shear waves.
