Abstract:

A method and system for detecting oil quality. The quality of engine oil can be determined utilizing an acoustic wave sensor to obtain viscosity and corrosivity data associated with the engine oil. The acoustic wave sensor is coated with a material that selectively reacts to at least one type of an acid in order to provide data indicative of the presence of the acids in the engine oil. The etch rate or the corrosivity of the engine oil can be determined based on the frequency data obtained as a result of the frequency measurement utilizing the acoustic wave sensor. The viscosity of the engine oil can additionally be obtained based on a measurement of phase and amplitude obtained from the data utilizing the acoustic wave sensor. The etch rate and the viscosity measurement provide data indicative of the quality of the engine oil.

Abstract:

A lubricity sensor includes a flexural plate wave device and a face shear mode bulk acoustic wave device, which is associated with and located proximate to the flexural plate wave device. The face shear mode bulk acoustic wave device and the flexural plate wave device form a lubricity sensor wherein acoustic wave data produced by the flexural plate device together with the face shear mode bulk acoustic wave device when the lubricity sensor is exposed to a liquid relates directly to a lubricity of the liquid thereby providing lubricity measurement data associated with the liquid. The acoustic wave data can comprises the oscillation gain compensation, the frequency, amplitude and/or phase velocity associated with the flexural plate device and the shear mode bulk acoustic wave device such that the oscillation gain compensation, the frequency, amplitude and/or phase velocity provide an indication of the lubricity of the liquid.

Abstract:

A wireless oil filter sensing system includes an oil filter and a sensing mechanism that is connectable to the oil filter. The sensing mechanism includes one or more acoustic wave sensing elements and at least one antenna that communicate with the acoustic wave sensing element(s). An external interrogation system could excite the acoustic wave sensing element(s) wireless and passively. When the acoustic wave sensing elements are in contact with oil contained in the oil filter, the acoustic wave sensing elements detect acoustic waves associated with the oil in response to an excitation of the acoustic wave sensing elements, thereby generating data indicative of the quality of the oil for wireless transmission through the antenna(s).

Abstract:

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.
