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).
